Check Digit Verification of cas no

The CAS Registry Mumber 1426657-68-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,6,5 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1426657-68:
(9*1)+(8*4)+(7*2)+(6*6)+(5*6)+(4*5)+(3*7)+(2*6)+(1*8)=182
182 % 10 = 2
So 1426657-68-2 is a valid CAS Registry Number.

Squaramide-tertiary amine catalyzed asymmetric cascade sulfa-Michael/ Michael addition via dynamic kinetic resolution: Access to highly functionalized chromans with three contiguous stereocenters

Yang, Wen,Yang, Yi,Du, Da-Ming

, p. 1190 - 1193 (2013)

An efficient asymmetric cascade sulfa-Michael/Michael addition reaction catalyzed by a chiral bifunctional squaramide-tertiary amine catalyst has been developed. This organocatalytic cascade reaction provides easy access to highly functionalized chromans with three contiguous stereocenters, including one quaternary center. In addition, a novel cascade sulfa Michael/retro-sulfa- Michael/sulfa-Michael/Michael reaction process, involving dynamic kinetic resolution, is described.
