Check Digit Verification of cas no

The CAS Registry Mumber 64975-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,9,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64975-72:
(7*6)+(6*4)+(5*9)+(4*7)+(3*5)+(2*7)+(1*2)=170
170 % 10 = 0
So 64975-72-0 is a valid CAS Registry Number.

A general synthesis of enantiopure 1,2-aminoalcohols via chiral morpholinones

Segat-Dioury, Fabienne,Lingibé, Olivier,Graffe, Bernadette,Sacquet, Marie-Claude,Lhommet, Gérard

, p. 233 - 248 (2007/10/03)

Eleven optically active 1,2-aminoalcohols 20a-i and 26b-c were prepared from D-phenylglycine via cyclic imines 7b-i (or enamine 7a). The key step of the strategy is the diastereoselective reduction of chiral oxazinones 7a-i.
