Check Digit Verification of cas no

The CAS Registry Mumber 1253377-15-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,3,7 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1253377-15:
(9*1)+(8*2)+(7*5)+(6*3)+(5*3)+(4*7)+(3*7)+(2*1)+(1*5)=149
149 % 10 = 9
So 1253377-15-9 is a valid CAS Registry Number.

Enantioselective addition of diethylzinc to aryl aldehydes catalyzed by novel chiral imino alcohol ligands

Salehi,Dabiri,Kozehgary

experimental part, p. 100 - 106 (2010/10/21)

The enantioselective alkylation of aryl aldehydes by diethylzinc in the presence of catalytic amounts of several novel chiral imino alcohol ligands, synthesized from the reaction of (R)-2-amino-1-butanol with aromatic aldehydes, was studied. The influence of temperature and ligand structure was investigated and enantioselectivity up to 81% was obtained.
