Check Digit Verification of cas no

The CAS Registry Mumber 201747-53-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,4 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 201747-53:
(8*2)+(7*0)+(6*1)+(5*7)+(4*4)+(3*7)+(2*5)+(1*3)=107
107 % 10 = 7
So 201747-53-7 is a valid CAS Registry Number.

Electrolytic Partial Fluorination of Organic Compounds. 24.1 Highly Regioselective Anodic Monofluorination of 2-Benzothiazolyl and 5-Chloro-2-benzothiazolyl Sulfides

Hou, Yankun,Higashiya, Seiichiro,Fuchigami, Toshio

, p. 9173 - 9176 (1997)

Electrochemical fluorination of 2-benzothiazolyl and 5-chloro-2-benzothiazolyl sulfides was successfully carried out using Et4NF·3HF as a supporting electrolyte and fluoride ion source in dimethoxyethane to provide the corresponding α-monofluorinated sulfides in good yields. Fluorination took place selectively at the position α to the sulfur atom of the sulfides, and the heterocyclic moieties were not fluorinated at all.
