Older Names Encountered in CAS Pre

At the changeover from the eighth to the ninth Collective Index periods (1972), the use of many older stem names was discontinued. These are all found in the older literature, and some can still be found in the literature today. The list in Table 3.3 equates many 9CI name fragments with those used in the SCI and earlier. An asterisk indicates that the name was used in SCI for the unsubstituted substance only substituted derivatives were indexed elsewhere.
