Check Digit Verification of cas no

The CAS Registry Mumber 137345-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,3,4 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137345-55:
(8*1)+(7*3)+(6*7)+(5*3)+(4*4)+(3*5)+(2*5)+(1*5)=132
132 % 10 = 2
So 137345-55-2 is a valid CAS Registry Number.

β-Phenylseleno α,β-unsaturated aldehydes, efficient three carbon homologating agents. 1,3-carbonyl transposition

Arrua,Comasseto

, p. 1663 - 1666 (2007/10/02)

The easily obtained β-phenylseleno α,β-unsaturated aldehydes react with Grignard reagents and with n-butyllithium leading to the 1,2-addition products, which upon acidic hydrolysis in the presence of silica gel afford the selenium-free α,β-unsaturated carbonyl compounds with 1,3-carbonyl transposition.
