Check Digit Verification of cas no

The CAS Registry Mumber 232273-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,2,2,7 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 232273-85:
(8*2)+(7*3)+(6*2)+(5*2)+(4*7)+(3*3)+(2*8)+(1*5)=117
117 % 10 = 7
So 232273-85-7 is a valid CAS Registry Number.

Syntheses of cyclobutane derivatives: Total synthesis of (+) and (-) enantiomers of the oleander scale Aspidiotus nerii sex pheromone

Boyer, Francois-Didier,Ducrot, Paul-Henri

, p. 1201 - 1211 (1999)

Synthesis of both enantiomers of the Aspidiotus nerii sex pheromone and their diastereomers has been achieved using, as a key step, an intramolecular ester enolate alkylation reaction for the formation of the cyclobutane ring with a good control of the relative configurations of the asymmetric centers. Stereoselective synthesis of a number of other trisubstituted cyclobutane derivatives also proves the versatility of the methodology used for the synthesis of the Aspidiotus nerii sex pheromone.
