Chii chinonzi CAS?
CAS inomirira Chemical Abstracts Service, dhatabhesi rine chiremera rakamiswa neAmerican Chemical Society (ACS.) Nhamba yeCAS, kana CAS registry nhamba, identifier yenhamba yakasiyana-siyana inoshandiswa kumaka zvinhu zvemakemikari, makomisheni, biological sequences, mapolima, nezvimwe. . Muindasitiri yemakemikari, iyo nhamba yeCAS chishandiso chakakosha nekuti inobatsira masayendisiti nemainjiniya zviri nyore uye nemazvo kuona uye kutora chaiwo makemikari zvinhu.
Kukosha kweNhamba yeCAS
Muindasitiri yemakemikari, kuzivikanwa uye kuteedzera zvinhu zvemakemikari ndechimwe chezvinhu zvakakosha zvebasa rezuva nezuva. Sezvo zvinhu zvemakemikari zvingave nemazita akawanda, mazita akajairika kana mazita emhando, izvi zvinogona kutungamirira kunyonganiso zviri nyore. nhamba yeCAS inogadzirisa dambudziko iri nekupa nhamba yakaenzana inoshandiswa pasi rose. Pasinei nekushandurwa kwezita kana mutauro wechinhu chemakemikari, nhamba yeCAS inogara ichienderana nechimwe chinhu. Iyi chaiyo nzira yekuzivikanwa yakakosha munzvimbo dzinoverengeka dzinosanganisira kutsvagisa nekusimudzira, kutenga, kugadzira uye kutevedzera mutemo.
Chimiro chenhamba yeCAS uye kukosha kwayo
Nhamba yeCAS inowanzova nezvikamu zvitatu: nhamba mbiri uye cheki digit. Semuenzaniso, nhamba yeCAS yemvura ndeye 7732-18-5. Ichi chimiro, kunyange chichiita sechiri nyore, chinotakura ruzivo rwakakura. Mavara matatu ekutanga anomiririra chinzvimbo chechinhu muChemical Abstracts Service, yechipiri seti yemanhamba inoratidza chakasarudzika chechinhu, uye cheki chekupedzisira chinoshandiswa kuona kuti manhamba apfuura akarurama. Kunzwisisa chimiro chenhamba dzeCAS kunobatsira nyanzvi kuti dzinzwisise nekukurumidza uye dzishandise.
CAS mune Chemical Indasitiri
Nhamba dzeCAS dzinoshandiswa zvakanyanya mukunyoresa, kudzora uye kutengeserana kwezvigadzirwa zvemakemikari. Munguva yekunyoresa uye kutengeswa kwezvigadzirwa zvemakemikari, nhamba dzeCAS dzinowanzodiwa nemasangano anodzora kuti ave nechokwadi chekuchengetedza uye kuve pamutemo kwemakemikari. Mukutengeserana nedzimwe nyika, nhamba dzeCAS dzinoshandiswawo kuona kuti vatengi nevatengesi vane ruzivo rwakafanana rwechigadzirwa chiri kutengeswa. Vatsvagiri vemakemikari vanofanirwawo kutaura nhamba dzeCAS pavanenge vachiburitsa mabhuku kana kunyorera patents kuti vaone chokwadi uye chokwadi chezvavakawana.
Maitiro ekushandisa nhamba dzeCAS kuwana ruzivo
Uchishandisa nhamba dzeCAS, varapi veindasitiri yemakemikari vanogona kunyatso tora ruzivo nezve kemikari zvinhu mune akawanda dhatabhesi. Semuyenzaniso, ruzivo rwekemikari yeSafety Data Sheet (SDS), muchetura, kukanganisa kwezvakatipoteredza, nzira yekugadzira uye mutengo wemusika zvese zvinogona kuwanikwa nekukurumidza uchishandisa nhamba yeCAS. Uku kugona kudzoreredza kwakanaka kwakakosha kumakambani eR&D kuita sarudzo uye kuongorora njodzi.
Kuenzaniswa kwenhamba dzeCAS nemamwe masisitimu ekuverenga
Kunyangwe nhamba dzeCAS dzichishandiswa zvakanyanya muindasitiri yemakemikari, mamwe masisitimu ekuverenga aripowo, senge nhamba yeUN yeUnited Nations kana nhamba yeEINECS yeEuropean Union. Mukuenzanisa, nhamba dzeCAS dzine kuvharika kwakakura uye kurongeka kwepamusoro. Izvi zvakakonzera kutonga kwenhamba dzeCAS muindasitiri yemakemikari pasi rose.
Mhedziso
CAS, sechiziviso chakamisikidzwa chemakemikari zvinhu, yave chishandiso chakakosha kuindasitiri yemakemikari. Kuburikidza nenhamba dzeCAS, makambani emakemikari nevatsvaguri vanokwanisa kubata nekushandisa ruzivo rwemakemikari zvinhu nemazvo uye nemazvo, nekudaro vachisimudzira kusimukira kweindasitiri uye kufambira mberi kwetekinoroji. Kunzwisisa uye nemazvo kushandisa nhamba yeCAS haingogone kuvandudza kushanda zvakanaka, asiwo zvinobudirira kudzivirira njodzi dzinogona kuitika.
