Check Digit Verification of cas no

The CAS Registry Mumber 51270-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,7 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 51270-22:
(7*5)+(6*1)+(5*2)+(4*7)+(3*0)+(2*2)+(1*2)=85
85 % 10 = 5
So 51270-22-5 is a valid CAS Registry Number.

Dynamic kinetic resolution: An efficient route to anti α-amino- β-hydroxy esters via Ru-SYNPHOS catalyzed hydrogenation

Mordant, Celine,Duenkelmann, Pascal,Ratovelomanana-Vidal, Virginie,Genet, Jean-Pierre

, p. 1296 - 1297 (2004)

The Ru(II)-catalyzed hydrogenation of α-amino-β-keto esters as their hydrochloride salts affords preparation of the corresponding anti α-amino-β-hydroxy esters under mild conditions with high diastereoselectivities and enantioselectivities via dynamic kinetic resolution.
