CAS (Chemical Abstracts Service) je oddelek Ameriškega kemijskega društva, ki je pooblaščen, da vsaki kemikaliji, ki je bila kdaj opisana v literaturi, dodeli enoznačni številčni identifikator. Namen identifikatorja je poenostaviti iskanje po bazah podatkov, ker imajo kemikalije pogosto več imen. Iskanje kemikalije s številko CAS omogočajo skoraj vse sodobne baze podatkov.
15. marca 2010 ob 23:38:46 je bilo v registru CAS 52.429.231 [[organska kemija|organskih]] in [[anorganska kemija|anorganskih]] spojin in 61.688.865 sekvenc.<ref>
CAS poleg dodeljevanja identifikatorjev tudi vzdržuje in prodaja baze podatkov teh kemikalij (CAS register). V registru so poleg kemikalij tudi zlitine, kompleksne spojine, [[mineral]]i, zmesi, polimeri, [[sol]]i in sekvence.
