Check Digit Verification of cas no

The CAS Registry Mumber 83339-20-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,3,3 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 83339-20:
(7*8)+(6*3)+(5*3)+(4*3)+(3*9)+(2*2)+(1*0)=132
132 % 10 = 2
So 83339-20-2 is a valid CAS Registry Number.

Une synthese hautement stereoselective de dienes conjugues (E)

Bloch, R.,Abecassis, J.,Hassan, D.

, p. 2019 - 2024 (2007/10/02)

A general method for the preparation of (E) terminal conjugated dienes was developed by the flash thermolysis of 2-substituted 2,5-dihydrothiophene-1,1-dioxides generated by a retro Diels-Alder reaction.This process allows the obtention of conjugated dienes, bearing or not a functionality (alcohols, esters), with an excellent stereoisomeric purity (in general higher than 98percent).An application to the synthesis of (E)-9,11-dodecadien-1-yl acetate, the major component of the sex pheromone of Diparopsis castanea, shows the generality and the efficacy of this method.
