Check Digit Verification of cas no

The CAS Registry Mumber 1426306-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,3,0 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1426306-75:
(9*1)+(8*4)+(7*2)+(6*6)+(5*3)+(4*0)+(3*6)+(2*7)+(1*5)=143
143 % 10 = 3
So 1426306-75-3 is a valid CAS Registry Number.

Bifunctional tertiary amine-squaramide catalyzed asymmetric catalytic 1,6-conjugate addition/aromatization of para-quinone methides with oxindoles

Deng, Yu-Hua,Zhang, Xiang-Zhi,Yu, Ke-Yin,Yan, Xu,Du, Ji-Yuan,Huang, Hanmin,Fan, Chun-An

, p. 4183 - 4186 (2016)

The asymmetric catalytic 1,6-addition of p-QMs with racemic oxindoles under the bifunctional catalysis of C2-symmetric dimeric Cinchona-derived squaramide is described. This tertiary amine-squaramide catalyzed reaction provides a diastereoselective and enantioselective approach to the effective assembly of diverse diarylmethine-substituted oxindoles having vicinal tertiary and quaternary stereocenters.
