Check Digit Verification of cas no

The CAS Registry Mumber 154658-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,6,5 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 154658-24:
(8*1)+(7*5)+(6*4)+(5*6)+(4*5)+(3*8)+(2*2)+(1*4)=149
149 % 10 = 9
So 154658-24-9 is a valid CAS Registry Number.

Transition metal-catalyzed asymmetric vinylcyclopropane-cyclopentene rearrangements. Asymmetric synthesis of cyclopentane derivatives using chiral sulfoxides as chiral sources

Hiroi,Arinaga

, p. 153 - 156 (1994)

Optically active α-olefinic cyclopropane derivatives, prepared by Michael addition of sodium bromomalonate to chiral vinylic sulfoxides followed by intramolecular asymmetric alkylation, led to facile transformation into chiral cyclopentane derivatives upo
