Check Digit Verification of cas no

The CAS Registry Mumber 1233219-48-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,2,1 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1233219-48:
(9*1)+(8*2)+(7*3)+(6*3)+(5*2)+(4*1)+(3*9)+(2*4)+(1*8)=121
121 % 10 = 1
So 1233219-48-1 is a valid CAS Registry Number.

Rhodium-catalyzed asymmetric hydrogenation of β-acetylamino acrylonitriles

Ma, Miaofeng,Hou, Guohua,Wang, Junru,Zhang, Xumu

experimental part, p. 506 - 511 (2011/06/17)

The rhodium-catalyzed asymmetric hydrogenation of β-acetylamino acrylonitriles was investigated by using monophosphine and bisphosphine ligands. It was found that an Rh-QuinoxP complex exhibited high enantioselectivities for β-aryl substituted β-acetylamino acrylonitriles and the Rh-JosiPhos CyPF-t-Bu complex was proven to be effective for the hydrogenation of tetrasubstituted olefins from cyclic β-acetylamino acrylonitriles.
