Check Digit Verification of cas no

The CAS Registry Mumber 1132829-55-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,2,8,2 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1132829-55:
(9*1)+(8*1)+(7*3)+(6*2)+(5*8)+(4*2)+(3*9)+(2*5)+(1*5)=140
140 % 10 = 0
So 1132829-55-0 is a valid CAS Registry Number.

Chiral Bronsted acid-mediated enantioselective organocatalytic three-component reaction for the construction of trifluoromethyl-containing molecules

Zhang, Guang-Wu,Wang, Lian,Nie, Jing,Ma, Jun-An

supporting information; experimental part, p. 1457 - 1463 (2009/07/18)

In combination with the advantages of organocatalysis, we have developed a highly enantioselective Friedel-Crafts aminoalkylation of indoles with imines generated in situ from trifluoroacetaldehyde methyl hemiacetal and aniline. Novel chiral trifluoromethyl-containing compounds were obtained in high yields with excellent enantioselectivities. This methodology was further extended to difluoroacetaldehyde methyl hemiacetal to demonstrate the broad scope of substrates.
