To search the database, enter either the: CAS Number or Name/ Synonym of a substance into the search engine.
Search Tips The database allows wildcard searching – the ability to replace letters/numbers with a symbol. In the database search screen ‘%’ is the wildcard symbol. For example to find all substances that have ‘sodium’ at the start of their name, you would enter sodium%. Or to find all substances that have ‘sodium’ within their name, you would enter %sodium%. As there are only a limited number of chemical synonyms in the database, searching via the CAS number is the most effective search method
