(8*3)+(7*4)+(6*3)+(5*2)+(4*3)+(3*3)+(2*7)+(1*4)=119
119 % 10 = 9
So 343233-74-9 is a valid CAS Registry Number.

A Direct Relationship between Nucleophilicity and Basicity in SN2 Reactions of Fluorenyl Anions with Benzyl Chloride in Dimethyl Sulfoxide Solution

Bordwell, Frederick G.,Hughes, David L.

, p. 3314 - 3320 (2007/10/02)

The rates of reactions for nine 9-substituted fluorenyl anions, 9-G-Fl- (G=CN, CO2Me, PhSO2, PhS, Ph, PhO, PhCH2, Me, t-Bu), reacting with benzyl chloride in Me2SO solution have been measured.For 9-CN-Fl- the rates increased with sol
