Check Digit Verification of cas no

The CAS Registry Mumber 1998156-24-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,9,9,8,1,5 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1998156-24:
(9*1)+(8*9)+(7*9)+(6*8)+(5*1)+(4*5)+(3*6)+(2*2)+(1*4)=243
243 % 10 = 3
So 1998156-24-3 is a valid CAS Registry Number.

Asymmetric synthesis of trifluoromethylated amines via catalytic enantioselective isomerization of imines

Wu, Yongwei,Deng, Li

supporting information, p. 14334 - 14337 (2012/10/30)

A new approach toward the asymmetric synthesis of optically active trifluoromethylated amines was enabled by an unprecedented, highly enantioselective catalytic isomerization of trifluoromethyl imines with a new chiral organic catalyst. Not only aryl but also alkyl trifluoromethylated amines could be obtained in high enantioselectivities.
