Nhamba yeCAS inorevei? Ongororo yakazara ye "identity makadhi" eindasitiri yemakemikari.
Muindasitiri yemakemikari, tinowanzo sangana neizwi CAS nhamba, inova yakakosha chiziviso mune zvakatemwa zvechigadzirwa, dhatabhesi remakemikari uye mashandiro ezuva nezuva. Zvingave mumadimikira echigadzirwa, dhatabhesi remakemikari, kana mumashandiro emazuva ese emakambani emakemikari, nhamba yeCAS chiziviso chakakosha.Nhamba yeCAS inorevei? Chinyorwa chino chichakupa mhinduro yakazara.
Nhamba yeCAS chii?
Nhamba yeCAS (Chemical Abstracts Service Number) identifier yakasarudzika yakapihwa neChemical Abstracts Service (CAS). Imwe neimwe kemikari, ingave yakasikwa kana yakagadzirwa, ine yakasarudzika nhamba yeCAS, iyo inovatendera kuti vanyatso kuzivikanwa uye kurondwa pasi rese.
Chimiro uye maitiro eiyo nhamba yeCAS
Nhamba yeCAS inowanzova nezvikamu zvitatu zvenhamba, semuenzaniso 64-17-5, inomiririra ruzivo rwakasiyana:

Chikamu chekutanga, chinogona kusiyana kubva pamanhamba maviri kusvika kunomwe, chinozivisa nhamba yakasiyana yechinhu chemakemikari;
Chikamu chechipiri chinogara chiri nhamba yemanhamba maviri, iyo inoshandiswa kugadzirisa chikamu chekutanga;
chikamu chechitatu idijiti yecheki imwe chete, iyo inoshandiswa kuona chokwadi chezvikamu zviviri zvekutanga zvenhamba.

Ichi chimiro chinobvumira nhamba dzeCAS kudzivirira kudzokorora uye inopa nzira yakamisikidzwa yekuziva makemikari zvinhu.
Iko Kushandiswa uye Kukosha kweCAS Nhamba
Kana tangonzwisisa zvinorehwa nenhamba yeCAS, isu tinodawo kunzwisisa kuti chii chaizvo chairi kushandiswa. chinangwa chikuru chenhamba yeCAS ndechekuona kuti chinhu chemakemikari chakasiyana uye chinozivikanwa pasi rose. Sezvo zvinhu zvemakemikari zvingave nemazita akawanda uye zvidhori, kushandiswa kwenhamba yeCAS kunodzivirira kuvhiringidzika. Semuenzaniso, Ethanol inogona kunzi doro, ethyl alcohol, nezvimwewo mumamiriro akasiyana, asi nhamba yavo yeCAS 64-17-5 yakasiyana, iyo inovimbisa kuti hapana kusanzwisisana pakukurukurirana pakati pemitauro yakasiyana uye nzvimbo.
Nhamba dzeCAS dzinoita basa rakakosha mukutenga, kushambadzira, kutsvagisa uye kutonga manejimendi muindasitiri yemakemikari. Semuyenzaniso, muSafety Data Sheets (SDS), nhamba dzeCAS dzinoshandiswa kuratidza zvakajeka zvinhu zvemakemikari zvinobatanidzwa kuitira kuti vanofarira vazive chaizvo izvo zvinhu uye njodzi dzinogona kuitika.
Kuwana uye Kubvunza Nhamba dzeCAS
Kana iwe uchida kutarisa iyo nhamba yeCAS yechinhu chemakemikari, unogona kutsvaga kuburikidza akati wandei online kemikari dhatabhesi, seCAS Registry, PubChem, nevamwe. Aya dhatabhesi anopa hupfumi hweruzivo pamusoro pemakemikari zvinhu, kusanganisira yavo nhamba dzeCAS, mamorekuru zvimiro, makemikari zvimiro, nezvimwe.
Kune makambani, kuve nenhamba dzeCAS dzakakwana hazvingobatsiri kutevedzera manejimendi, asi zvakare inovandudza kugona kwekutengesa ketani manejimendi. Semuenzaniso, kuve nechokwadi chekuti zvigadzirwa zvakatengwa zvakangofanana nemakemikari anodiwa kudzivirira nyaya dzemhando kana njodzi dzekutonga.
Mhedziso
Mhinduro kumubvunzo wezvinorehwa nenhamba yeCAS inodarika zvazvinoreva kune basa rayo risingadzoreki muindasitiri yemakemikari, kwainoita se 'chitupa chitupa' chemakemikari zvinhu, kuve nechokwadi chekuzivikanwa kwavo uye manejimendi pasi rose. Kunzwisisa uye nemazvo kushandisa nhamba dzeCAS hunyanzvi hwakakosha kune avo vanoshanda muindasitiri yemakemikari.
