Check Digit Verification of cas no

The CAS Registry Mumber 92745-07-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,7,4 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 92745-07:
(7*9)+(6*2)+(5*7)+(4*4)+(3*5)+(2*0)+(1*7)=148
148 % 10 = 8
So 92745-07-8 is a valid CAS Registry Number.

Syntheses of Mercaptobenzoic Acids and Mercaptopyridines Using Elemental Sulfur in the Presence of NaOH-KOH

Kamiyama, Tsutomu,Enomoto, Saburo,Inoue, Masami

, p. 5184 - 5189 (2007/10/02)

Mercaptobenzoic acids and mercaptopyridines were synthesized by using mercaptylation of halogeno compounds with elemental sulfur in the presence of molten salts (NaOH-KOH).This procedure was also applied to the preparation of selenoaryl compounds by using elemental selenium.Based on the behavior of the molten salts and sulfur, Na2S and K2S were considered to be the active species for the mercaptylation.KEYWORDS-mercaptylation; molten salt; o-mercaptobenzoic acid; o-selenobenzoic acid; 2-mercaptopyridine
