Check Digit Verification of cas no

The CAS Registry Mumber 199335-58-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,3,3 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 199335-58:
(8*1)+(7*9)+(6*9)+(5*3)+(4*3)+(3*5)+(2*5)+(1*8)=185
185 % 10 = 5
So 199335-58-5 is a valid CAS Registry Number.

4-hydroxycoumarin derivatives. Part XIII (1). 3-(2'-alkylthioethyl-1'-phenyl)-4-hydroxycoumarins and their oxidation products

Sulko, Jerzy

, p. 319 - 324 (2007/10/03)

3-(2'-Methylthioethyl-1'-phenyl)-4-hydroxycoumarin and 3-(2'-ethylthioethyl-1'-phenyl)-1-hydroxycoumarin were synthesized. Acetylation of these compounds with acetic anhydride and pyridine yielded respective 4-acetylcoumarins while appropriate sulfoxides and sulfones were obtained by oxidation of alkylthio substituens with H2O2. 3-(2'-ethylthioethyl-1'-phenyl)-4-hydroxycoumarin methylated with diazomethane gave 3-(2'-ethylthioethyl-1'-phenyl)-4-methoxycoumarin and 2-methoxy-3-(2'-ethylthioethyl-1'-phenyl)-chromone.
