Check Digit Verification of cas no

The CAS Registry Mumber 57959-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,5 and 9 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57959-50:
(7*5)+(6*7)+(5*9)+(4*5)+(3*9)+(2*5)+(1*0)=179
179 % 10 = 9
So 57959-50-9 is a valid CAS Registry Number.

Enantioselective Rhodium-Catalyzed Addition of Arylboroxines to N-Unprotected Ketimines: Efficient Synthesis of Cipargamin

Zhu, Jinbin,Huang, Linwei,Dong, Wei,Li, Naikai,Yu, Xingxin,Deng, Wei-Ping,Tang, Wenjun

, p. 16119 - 16123 (2019)

Highly enantioselective rhodium-catalyzed addition of arylboroxines to N-unprotected ketimines is realized for the first time by employing chiral BIBOP-type ligands with a Rh loading as low as 1 mol %. A range of chiral α-trifluoromethyl-α,α-diaryl α-tertiary amines or 3-amino-3-aryloxindoles were formed with excellent ee values and yields by employing either WingPhos or PFBO-BIBOP as the ligand. The method has enabled an efficient enantioselective synthesis of cipargamin.
