88141-39-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 88141-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,4 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 88141-39:
(7*8)+(6*8)+(5*1)+(4*4)+(3*1)+(2*3)+(1*9)=143
143 % 10 = 3
So 88141-39-3 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 (2018/11/30)

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).
