Check Digit Verification of cas no

The CAS Registry Mumber 20434-79-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,3 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20434-79:
(7*2)+(6*0)+(5*4)+(4*3)+(3*4)+(2*7)+(1*9)=81
81 % 10 = 1
So 20434-79-1 is a valid CAS Registry Number.

Synthesis of chiral sultams via palladium-catalyzed intramolecular asymmetric reductive amination

Song, Bo,Yu, Chang-Bin,Ji, Yue,Chen, Mu-Wang,Zhou, Yong-Gui

, p. 1704 - 1707 (2017)

A novel palladium-catalyzed intramolecular reductive amination of ketones with weakly nucleophilic sulfonamides has been developed in the presence of a Br?nsted acid, giving a wide range of chiral γ-, δ-, and ε-sultams in high yields and up to 99% of enan
