Check Digit Verification of cas no

The CAS Registry Mumber 1613639-23-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,6,3 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1613639-23:
(9*1)+(8*6)+(7*1)+(6*3)+(5*6)+(4*3)+(3*9)+(2*2)+(1*3)=158
158 % 10 = 8
So 1613639-23-8 is a valid CAS Registry Number.

Bi-aryl rotation in phenyl-dihydroimidazoquinoline catalysts for kinetic resolution of arylalkyl carbinols

Wang, Zheng,Ye, Jinjin,Wu, Rui,Liu, Yang-Zi,Fossey, John S.,Cheng, Jiagao,Deng, Wei-Ping

, p. 1909 - 1913 (2014)

Chiral nucleophilic catalysts, 6-aryl-phenyl-dihydroimidazoquinolines (PIQs), were designed, synthesised and applied to the kinetic resolution of arylalkyl carbinols with very high selectivity (S) factors (up to 530). Density functional theory calculations indicate that multiple noncovalent interactions play a key role in chiral recognition between 6-aryl-PIQ catalysts and chiral secondary alcohol substrates.
