Check Digit Verification of cas no

The CAS Registry Mumber 1268720-12-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,7,2 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1268720-12:
(9*1)+(8*2)+(7*6)+(6*8)+(5*7)+(4*2)+(3*0)+(2*1)+(1*2)=162
162 % 10 = 2
So 1268720-12-2 is a valid CAS Registry Number.

Highly efficient organocatalytic kinetic resolution of activated nitroallylic acetates with aldehydes via conjugate addition-elimination

Reddy, Raju Jannapu,Chen, Kwunmin

, p. 1458 - 1461 (2011)

A novel, efficient, and unprecedented organocatalytic kinetic resolution has been developed. For the first time, a variety of nitroallylic acetates 1a-i have been resolved with aldehydes in the presence of 2 (2.5 mol %) via conjugate addition-elimination.

Kinetic resolution of activated nitroallylic acetates with aldehydes and ketones through a conjugate addition-elimination SN2′ process

Jannapu Reddy, Raju,Lee, Pei-Hsun,Magar, Dhananjay R.,Chen, Jung-Hsuan,Chen, Kwunmin

experimental part, p. 353 - 365 (2012/02/04)

A unique organocatalytic kinetic resolution (KR) of nitroallylic acetates has been developed. A variety of racemic nitroallylic acetates (1a-n) were resolved with chiral enamines formed in situ from the reaction of aldehydes and ketones with organocatalys
