ACS Headquarters,

Washington, D.C.

CAS is a division of the American ChemicalSociety

  • ACS is a not-for-profit society of more than 130 years

  • the largest scientific society, with nearly 163,000 members

  • a mission “to encourage the increase and diffusion of chemical knowledge” for the benefit of industry and education

CAS (Chemical Abstracts Service)

American Chemical Society

In 1876



Washington D.C.




In 1907

Chemical Abstracts Service(columbus)


CAS moved to its present location in 1965

New Data Center


CAS occupies three buildings on a 52 acre site.

Our data center is the "nerve center" for online users worldwide

and enables them to search CAS data

CAS (Chemical Abstracts Service) worldwide

Our mission is to create the world’s best digital environment to search, retrieve, analyze and link chemical information

SciFinder worldwide
