Chemical Abstracts, or CA for short, is the world's most important review organ for chemistry and related fields, edited and published by the Chemical Abstracts Service (CAS). The CAS assigns a registration number (CAS No. or CARNO, Chemical Abstracts Registeratory Number) to each chemical compound, by which it is clearly identified.
