Check Digit Verification of cas no

The CAS Registry Mumber 1253121-03-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,1,2 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1253121-03:
(9*1)+(8*2)+(7*5)+(6*3)+(5*1)+(4*2)+(3*1)+(2*0)+(1*3)=97
97 % 10 = 7
So 1253121-03-7 is a valid CAS Registry Number.

Enantioselective synthesis of syn - And anti -1,3-aminoalcohols via β-aminoketones and subsequent reduction/dynamic kinetic asymmetric transformation

Millet, Renaud,Traeff, Annika M.,Petrus, Michiel L.,Baeckvall, Jan-E.

supporting information; experimental part, p. 15182 - 15184 (2011/01/05)

β-Aminoketones obtained from imines in an organocatalytic Mannich reaction were transformed to enantio- and diastereomerically pure 1,3-aminoalcohols with two stereogenic centers via a combined reduction/dynamic kinetic asymmetric transformation. Both syn and anti diastereomers were obtained in high yield, dr, and ee.
