Check Digit Verification of cas no

The CAS Registry Mumber 76440-47-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,4 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76440-47:
(7*7)+(6*6)+(5*4)+(4*4)+(3*0)+(2*4)+(1*7)=136
136 % 10 = 6
So 76440-47-6 is a valid CAS Registry Number.

Addition of Aromatic Thiols to Conjugated Cycloalkenones, Catalyzed by Chiral β-Hydroxy Amines. A Mechanistic Study on Homogeneous Catalytic Asymmetric Synthesis

Hiemstra, Henk,Wynberg, Hans

, p. 417 - 430 (1981)

Reactions between aromatic thiols and conjugated cycloalkenones afford optically active 3-arylthiocycloalkanones, when chiral bases are used as catalysts.This paper reports a detailed investigation into the mechanism of this catalytic asymmetric synthesis
