Check Digit Verification of cas no

The CAS Registry Mumber 163772-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,7,7 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 163772-78:
(8*1)+(7*6)+(6*3)+(5*7)+(4*7)+(3*2)+(2*7)+(1*8)=159
159 % 10 = 9
So 163772-78-9 is a valid CAS Registry Number.

Intramolecular Anti-Carbolithiation of Alkynes: Stereo-Directing Effect of Lithium-Coordinating Substituents

Ly, Kim Uyen,Boussonnière, Anne,Castanet, Anne-Sophie

, (2022/01/19)

This paper presents the results of our investigations on the stereochemical course of intramolecular carbolithiation of alkynes. It is shown that the presence of a lithium-chelating propargylic substituent completely reverses the otherwise favored syn-pro
