Check Digit Verification of cas no

The CAS Registry Mumber 123312-24-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,3,1 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 123312-24:
(8*1)+(7*2)+(6*3)+(5*3)+(4*1)+(3*2)+(2*2)+(1*4)=73
73 % 10 = 3
So 123312-24-3 is a valid CAS Registry Number.

Application of the chiral bis(phosphine) monoxide ligand to catalytic enantioselective addition of dialkylzinc reagents to β-nitroalkenes

Cote, Alexandre,Lindsay, Vincent N. G.,Charette, Andre B.

, p. 85 - 87 (2007/10/03)

(Chemical Equation Presented) Me-DuPHOS monoxide is shown to be a very effective ligand in the enantioselective copper-catalyzed addition of dialkylzinc reagents to β-nitroalkenes providing access to chiral nitroalkanes. The major advantages of this process are high yields, broad and complementary substrate scope, and high enantioselectivities. The effect of achiral dummy ligands as an additive has also been documented.
