Check Digit Verification of cas no

The CAS Registry Mumber 202577-48-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,5,7 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 202577-48:
(8*2)+(7*0)+(6*2)+(5*5)+(4*7)+(3*7)+(2*4)+(1*8)=118
118 % 10 = 8
So 202577-48-8 is a valid CAS Registry Number.

Synthesis of pyridinium dinitrobenzyl sufates and potassium (Dinitrobenzyl β-D-glucopyranosid) uronates

Mori, Masa-Aki,Dohrin, Masahiro,Sayama, Michio,Shoji, Miki,Inoue, Masami,Kozuka, Hiroshi

, p. 145 - 147 (2007/10/03)

Sulfates and glucoronides of 2,4-dinitrobenzyl alcohol 1a an 2,6- dinitrobenzyl alcohol 1b, which are major or putative metabolites of 2,4- dinitrotoluene (2,4-DNT) and 2,6-dinitrotoluene (2,6-DNT), were synthesized from 1a and 1b by reaction with pyridinium sulfonate and methyl (2,3,4-tri- O-acetyl-α-D-glucopyranosyl)uronate bromide 3, respectively, as their pyridinium salts (2a, 2b) and potassium salts (6a, 6b). These conugates are important for the study of carcinogenicity of 2,4-DNT and 2,6-DNT.
