Check Digit Verification of cas no
The CAS Registry Mumber 1632196-93-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,2,1,9 and 6 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1632196-93:
(9*1)+(8*6)+(7*3)+(6*2)+(5*1)+(4*9)+(3*6)+(2*9)+(1*3)=170
170 % 10 = 0
So 1632196-93-0 is a valid CAS Registry Number.

Copper-Promoted N-Arylation of the Indole Side Chain of Tryptophan Using Triarylbismuthines
Le Roch, Adrien,Chan, Hwai-Chien,Gagnon, Alexandre
, p. 5815 - 5819 (2020)
A simple protocol for the regioselective N-arylation of the indole side chain of tryptophan using triarylbismuth reagents as the arylating agent is reported. The reaction is catalyzed by copper(II) acetate, and operates in the presence of triethylamine or
