Nhamba yeCAS chii?
Nhamba yeCAS, inozivikanwa seChemical Abstracts Service Number (CAS), inhamba yekuzivikanwa yakasarudzika yakapihwa chinhu chemakemikari neUS Chemical Abstracts Service (CAS). Chese chinozivikanwa chemakemikari chinhu, kusanganisira zvinhu, makomisheni, musanganiswa, uye biomolecules, inopihwa chaiyo CAS nhamba. Iyi manhamba sisitimu inoshandiswa zvakanyanya mumaindasitiri ezvemakemikari, emishonga, uye ezvekushandisa uye inotarisirwa kupa chiyero chepasi rose chinowirirana chekuzivikanwa kwemakemikari zvinhu.
Chimiro uye Zvinorehwa Nhamba yeCAS
Nhamba yeCAS ine nhamba nhatu mufomati "XXX-XX-X". Madijiti matatu ekutanga iserial number, maviri epakati anoshandiswa pakutarisa, uye yekupedzisira digit icheki digit. Iyi sisitimu yenhamba yakagadzirirwa kuona kuti kemikari yega yega ine chiziviso chakasiyana, kudzivirira kuvhiringika nekuda kwemazita akasiyana kana mutauro. Semuenzaniso, iyo nhamba yeCAS yemvura ndeye 7732-18-5, uye chirevo chenhamba iyi chinonongedza kune imwechete kemikari chinhu zvisinei nenyika kana indasitiri.
Kukosha kwenhamba dzeCAS nenzvimbo dzekushandisa
Kukosha kwenhamba yeCAS kunonyanya kuratidzwa mune zvinotevera zvinhu:

Kuzivikanwa kwemakemikari epasi rose: Nhamba yeCAS inopa chitupa chakasiyana chepasi rose chechimwe chinhu chemakemikari. Zvingave muzvinyorwa zvesainzi, mashandisirwo emvumo, kunyorwa kwechigadzirwa kana mapepa ekuchengetedza data, nhamba yeCAS inoshanda seyakafanana chiyero uye inovimbisa ruzivo rwakafanana.

Data Management uye Retrieval: Nekuda kwezvakasiyana-siyana zvemakemikari zvinhu uye yavo yakaoma nomenclature, nhamba dzeCAS dzinoita kuti manejimendi uye kudzoreredzwa kwemakemikari dhatabhesi zvakanyanya. Vatsvagiri, makambani emakemikari uye masangano ehurumende anogona kukurumidza uye nemazvo kuwana ruzivo rwezvemakemikari zvinhu kuburikidza nenhamba dzeCAS.

Regulatory kutevedzera uye kuchengetedza manejimendi: Mukutonga kwemakemikari, nhamba dzeCAS chishandiso chakakosha chekuona kutevedza kwemitemo. Mitemo mizhinji yenyika uye yedunhu remakemikari, seKunyoreswa, Kuongorora, Mvumo uye Kudzora Kemikari (REACH) uye Toxic Substances Control Act (TSCA), inoda nhamba dzeCAS kuti ive nechokwadi chepamutemo uye kuchengetedzeka kwemakemikari zvinhu.

Ndinowana sei nekushandisa nhamba yeCAS?
Nhamba dzeCAS dzinowanzowanikwa kuburikidza nedhatabhesi dzakakosha kana mabhuku emakemikari, akadai seCAS Registry, PubChem, ChemSpider, etc. Paunenge uchishandisa nhamba yeCAS, zvakakosha kuve nechokwadi kuti nhamba yakapinda yakarurama, sezvo kunyange kukanganisa kwedijiti imwe chete kunogona kuita kuti chinhu chakasiyana zvachose chemakemikari chinotorwa. Nhamba dzeCAS dzinowanzo shandiswa mukugadzira makemikari uye maitiro ekutsvagisa ekutenga, kutonga kwemhando, uye kugadzirira uye manejimendi ekuchengetedza data mapepa.
Summary
Seyakashandiswa pasi rese kemikari yekuzivikanwa sisitimu, nhamba yeCAS inovandudza zvakanyanya mashandiro uye nemazvo ekudzoreredza ruzivo rwemakemikari. Nhamba dzeCAS dzinoita basa risingadzokerike muindasitiri yemakemikari, kungave mukutsvagisa nekugadzira, kana mukuteerera kwemitemo uye kuchengetedza manejimendi. Naizvozvo, kunzwisisa uye nemazvo kushandisa nhamba dzeCAS kwakakosha kune varapi veindasitiri yemakemikari.
