CAS Source Index (CASSI) Search Tool
“The CASSI Search Tool is a free resource that can be used to quickly and easily look up or confirm publication titles and abbreviations in an accessible electronic format. It is provided by CAS as a public service. The CASSISM database contains a listing of publications indexed by CAS since 1907, including serial and non-serial scientific and technical publications. The database will be updated annually and was last updated in December 2009.”
