Check Digit Verification of cas no

The CAS Registry Mumber 1320256-74-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,0,2,5 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1320256-74:
(9*1)+(8*3)+(7*2)+(6*0)+(5*2)+(4*5)+(3*6)+(2*7)+(1*4)=113
113 % 10 = 3
So 1320256-74-3 is a valid CAS Registry Number.

Enantioselective copper-catalyzed conjugate addition of trimethylaluminum to β,γ-unsaturated α-ketoamides: Efficient access to γ-methyl-substituted carbonyl compounds

Goncalves-Contal, Sylvie,Gremaud, Ludovic,Alexakis, Alexandre

, p. 12701 - 12704 (2013/12/04)

Picture perfect: By using the reagent trimethylaluminium and β,γ-unsaturated α-ketoamides, 1,4-adducts were obtained with perfect 1,4-regioselectivity and good to excellent yields and ee values. The potential synthetic utility of the methodology was highl
