808770-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 808770-44-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,8,7,7 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 808770-44:
(8*8)+(7*0)+(6*8)+(5*7)+(4*7)+(3*0)+(2*4)+(1*4)=187
187 % 10 = 7
So 808770-44-7 is a valid CAS Registry Number.

ASYMMETRIC IMINE HYDROGENATION PROCESSES

-

Page/Page column 31, (2008/06/13)

A process for the catalytic hydrogenation or asymmetric hydrogenation of imines of Formula (I) to the corresponding amines of Formula (II) is provided in which R1 is aryl ; R2 is aryl, cyclic, alkyl, alkenyl or alkynyl; and R3 is alky l. The catalytic system includes a ruthenium complex containing (1) a diamine and (2) a diphosphine or two monodentate phosphines ligands. Such process also relates to the asymmetric hydrogenation of prochiral imines to the chiral amines using chiral ruthenium complexes bearing chiral diphosphines or chiral monodentate phosphines and chiral diamines.
