Chemical Abstracts Service (CAS) Registry Numbers are numeric identifiers that can contain from 4 up to 10 digits, divided by hyphens into three parts. The third part is a check digit.
The resource function ValidCASNumberQ can be used to validate a CAS Registry Number.
ResourceFunction["CommonChemistryLookup"] also accepts Entity objects with the "Chemical" type.
ResourceFunction["CommonChemistryLookup"] returns an Association.
