Check Digit Verification of cas no

The CAS Registry Mumber 82120-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,2 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82120-45:
(7*8)+(6*2)+(5*1)+(4*2)+(3*0)+(2*4)+(1*5)=94
94 % 10 = 4
So 82120-45-4 is a valid CAS Registry Number.

SYNTHESE D'ENONES CYCLIQUES ET D'ACIDES DIENIQUES PAR REACTION DE WITTIG HORNER EMMONS

Canevet, J. C.,Sharrard, F.

, p. 181 - 184 (1982)

Enol lactones react with methyl diethylphosphonacetate to give directly cyclic 2-en 1-ones with a carbomethoxy substituent in the 2 position, while 5-OH 2(5H) furanones afford stereospecifically Z,E-dienic acids.
