Check Digit Verification of cas no

The CAS Registry Mumber 1400693-91-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,0,6,9 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1400693-91:
(9*1)+(8*4)+(7*0)+(6*0)+(5*6)+(4*9)+(3*3)+(2*9)+(1*1)=135
135 % 10 = 5
So 1400693-91-5 is a valid CAS Registry Number.

Chiral Bronsted acid-catalyzed diastereo- and enantioselective synthesis of CF3-substituted aziridines

Chai, Zhuo,Bouillon, Jean-Philippe,Cahard, Dominique

, p. 9471 - 9473 (2012/10/30)

A multicomponent organocatalyzed highly diastereo- and enantioselective synthesis of CF3-substituted aziridines is described. This reaction of in situ generated CF3CHN2 and aldimines was realized by chiral Bronsted acid catalysis. The utility of the products is illustrated by easy access to β-CF3 isocysteine and aziridine-containing dipeptides.
