Check Digit Verification of cas no

The CAS Registry Mumber 117775-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,7,7 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 117775-93:
(8*1)+(7*1)+(6*7)+(5*7)+(4*7)+(3*5)+(2*9)+(1*3)=156
156 % 10 = 6
So 117775-93-6 is a valid CAS Registry Number.

General-Base Catalysis of Nucleophilic Substitution at Carbon

Dietze, Paul E.,Jencks, William P.

, p. 340 - 344 (1989)

The bimolecular reaction of methyl(4-nitrophenyl)sulfonium ion with trifluoroethanol is catalyzed by substituted acetate ions and other buffer bases in 50percent trifluoroethanol-water (v/v) at 40 deg C and ionic strength 0.5 M (NaClO4).The Broensted β value is 0.26, but there is no significant solvent deuterium isotope effect.The reaction with water and ethanol do not show catalysis and there is no catalysis of the reaction of (4-trifluoromethyl)benzyl bromide.
