Check Digit Verification of cas no

The CAS Registry Mumber 1364041-33-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,4,0,4 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1364041-33:
(9*1)+(8*3)+(7*6)+(6*4)+(5*0)+(4*4)+(3*1)+(2*3)+(1*3)=127
127 % 10 = 7
So 1364041-33-7 is a valid CAS Registry Number.

Asymmetric michael addition of α-substituted isocyanoacetates with maleimides catalyzed by chiral tertiary amine thiourea

experimental part, p. 2947 - 2953 (2012/05/20)

A highly diastereoselective and enantioselective Michael addition of α-substituted isocyanoacetates with maleimides catalyzed by bifunctional tertiary amine thioureas has been developed. Various chiral succinimide derivatives bearing adjacent quaternary and tertiary stereocenters were prepared in excellent yields (up to 98%), diastereoselectivities (up to 99:1), and enantioselectivities (up to 98% ee). The synthetic utility of chiral succinimide derivatives is also demonstrated in the preparation of h5-HT1d receptor agonist motifs.
