CAS Headquarters Complex, completed in 1965 with addition (on left) in 1973. Columbus, Ohio. Chemical Abstracts (CA) began as a volunteer effort and developed from there. The use of volunteer abstractors was phased out in 1994. Chemical Abstracts has been associated with the American Chemical Society in one way or another since 1907. [13]

Built into every CAS number is a check-digit that makes it possible to detect mis-typed numbers. Validation is a mathematical and repetitive process well-suited for software. Note that a validated CAS number can still be absent from the CAS database; mathematical validation only says that a CAS number could be valid based on its format. [1]
