Check Digit Verification of cas no

The CAS Registry Mumber 746652-66-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,6,6,5 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 746652-66:
(8*7)+(7*4)+(6*6)+(5*6)+(4*5)+(3*2)+(2*6)+(1*6)=194
194 % 10 = 4
So 746652-66-4 is a valid CAS Registry Number.

Regioselective and stereoselective nucleophilic ring opening of trifluoromethylated cyclic sulfates: Asymmetric synthesis of both enantiomers of syn-(3-trifluoromethyl)isoserine

Jiang, Zhong-Xing,Qing, Feng-Ling

, p. 5486 - 5489 (2007/10/03)

A novel and efficient enantioselective synthesis of both enantiomers of syn-(3-trifluoromethyl)isoserine was achieved. Ring opening of trifluoromethylated cyclic sulfates 3, derived from enantiopure trifluoromethylated vicinal diols 2, with various nucleo
