1357917-61-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1357917-61-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,7,9,1 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1357917-61:
(9*1)+(8*3)+(7*5)+(6*7)+(5*9)+(4*1)+(3*7)+(2*6)+(1*1)=193
193 % 10 = 3
So 1357917-61-3 is a valid CAS Registry Number.

Cu-catalyzed asymmetric [3+2] cycloaddition of α-iminoamides with activated olefins
Gonzalez-Esguevillas, Maria,Adrio, Javier,Carretero, Juan C.
, p. 2149 - 2151 (2012/03/11)
A variety of 2-amido pyrrolidines, including Weinreb-type amides, have been prepared with very high exo diastereoselectivity and enantioselectivitiy in the reaction of α-iminoamides with activated alkenes catalyzed by Cu I-Segphos ligands.
