title: Comments on the significance of the quasi-valence number for chemical carcinogenesis.
abstract: A quasi-valence number of less than 3.20 was reported to be significant in correlating carcinogenicity. This criterion has no meaningful relationship since such a large proportion of organic compounds fall in this group that it provides no selectivity.
