Scopus provides chemical search by CAS number and by chemical name, while WoS does not have these features. On the other hand, WoS has chemical structure search, but only a small number of publications are actually indexed for chemical structure searches. SciFinder is the preferred option for chemical searches is all cases.
The identification of the chemicals on the Cards is based on the UN numbers, the Chemical Abstracts Service (CAS) number and the Registry of Toxic Effects of Chemical Substances (RTECS/NIOSH) numbers. It is thought that the use of those three systems assures the most unambiguous method of identifying the chemical substances concerned, referring ...
