Check Digit Verification of cas no

The CAS Registry Mumber 26321-38-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,3,2 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26321-38:
(7*2)+(6*6)+(5*3)+(4*2)+(3*1)+(2*3)+(1*8)=90
90 % 10 = 0
So 26321-38-0 is a valid CAS Registry Number.

Preparation of Indolenines via Nucleophilic Aromatic Substitution

Huber, Florian,Roesslein, Joel,Gademann, Karl

, p. 2560 - 2564 (2019/03/19)

An unusual aromatic substitution to access indolenines is described. 2-(2-Methoxyphenyl)acetonitrile derivatives are reacted with various alkyl and aryl Li reagents to furnish the corresponding indolenine products, constituents of natural products, and cyanine dyes such as indocyanine green. This new method was used to synthesize 41 indolenines with large functional group tolerance, and selected examples were further converted to the corresponding indolenine dyes. Key experiments provide insight into the mechanism of this nucleophilic aromatic substitution.
