Check Digit Verification of cas no

The CAS Registry Mumber 71963-96-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,6 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 71963-96:
(7*7)+(6*1)+(5*9)+(4*6)+(3*3)+(2*9)+(1*6)=157
157 % 10 = 7
So 71963-96-7 is a valid CAS Registry Number.

, p. 381 - 396 (2007/10/03)

It was found that the desulfonylation reaction of α,α-dialkylated (E)-allylic sulfones with a base preferentially affords the sterically unfavorable (Z)-alkadienes. The relative degree of the "syn-effect", which is herein defined as an effect which stabil
