Check Digit Verification of cas no

The CAS Registry Mumber 1431769-22-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,7,6 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1431769-22:
(9*1)+(8*4)+(7*3)+(6*1)+(5*7)+(4*6)+(3*9)+(2*2)+(1*2)=160
160 % 10 = 0
So 1431769-22-0 is a valid CAS Registry Number.

An asymmetric Michael addition of α,α-disubstituted aldehydes to maleimides leading to a one-pot enantioselective synthesis of lactones catalyzed by amino acids

Kokotos, Christoforos G.

supporting information, p. 2406 - 2409 (2013/06/27)

A cheap and fast construction of both enantiomers of substituted succinimides is reported. α- or β-amino acids, such as β-phenylalanine and α-tert-butyl aspartate, were found to be efficient organocatalysts for the reaction between α,α-disubstituted aldeh
