Check Digit Verification of cas no

The CAS Registry Mumber 881663-41-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,6,6 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 881663-41:
(8*8)+(7*8)+(6*1)+(5*6)+(4*6)+(3*3)+(2*4)+(1*1)=198
198 % 10 = 8
So 881663-41-8 is a valid CAS Registry Number.

Process for the production of chiral propionic acid derivatives

-

Page/Page column 9, (2010/02/11)

The present invention is concerned with a novel process for the preparation of compounds of formula I comprising catalytic asymmetric hydrogenation of a compound of formula (II) in the presence of a catalyst comprising ruthenium and a chiral diphosphine ligand or comprising rhodium and a chiral diphosphine ligand, wherein R1, R2, R3 and R4 are as defined in the specification and claims. The compounds of formula I and the corresponding salts and/or esters are pharmaceutically active substances.
