Check Digit Verification of cas no

The CAS Registry Mumber 74457-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74457-31:
(7*7)+(6*4)+(5*4)+(4*5)+(3*7)+(2*3)+(1*1)=141
141 % 10 = 1
So 74457-31-1 is a valid CAS Registry Number.

Aldol Reaction of Aluminium Enolate Resulting from 1,4-Addition of R2AlX to α,β-Unsaturated Carbonyl Compound. A 1-Acylethenyl Anion Equivalent

Itoh, Akira,Ozawa, Shuji,Oshima, Koichiro,Nozaki, Hitosi

, p. 274 - 278 (1981)

Organoaluminium reagents R2AlX (X=SPh, SeMe) easily add to α,β-unsaturated carbonyl compounds in 1,4-fashion.The resulting aluminium enolates react with aldehydes to give aldol adducts in fair to good yields.Formal elimination of HX from the adducts provi
