Check Digit Verification of cas no

The CAS Registry Mumber 74457-32-2 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 74457-32:
(7*7)+(6*4)+(5*4)+(4*5)+(3*7)+(2*3)+(1*2)=142
142 % 10 = 2
So 74457-32-2 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 (2007/10/02)

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

ALDOL REACTION OF ALUMINIUM ENOLATE RESULTING FROM 1,4-ADDITION OF Me2AlSPh TO α,β-UNSATURATED CARBONYL COMPOUND. A 1-ACYLETHENYL ANION EQUIVALENT

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

, p. 361 - 364 (2007/10/02)

Me2AlSPh or Me2AlSeMe adds to α,β-unsaturated carbonyl compounds in 1,4-fashion.The resulting aluminium enolates react with aldehydes effectively to afford the adducts of the title anion after formal PhSH (or MeSeH)-elimination
