Check Digit Verification of cas no

The CAS Registry Mumber 1453494-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,3,4,9 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1453494-27:
(9*1)+(8*4)+(7*5)+(6*3)+(5*4)+(4*9)+(3*4)+(2*2)+(1*7)=173
173 % 10 = 3
So 1453494-27-3 is a valid CAS Registry Number.

Synthesis of chiral seven-membered β-substituted lactams: Via Rh-catalyzed asymmetric hydrogenation

Huang, Yi,Li, Pan,Dong, Xiu-Qin,Zhang, Xumu

, p. 8819 - 8823 (2018)

Rh/bisphosphine-thiourea ligand (ZhaoPhos)-catalyzed asymmetric hydrogenation of seven-membered β-substituted α,β-unsaturated lactams was successfully developed to prepare various chiral seven-membered β-substituted lactams with good to excellent results (up to >99% conversion, 99% yield, and >99% ee).
