Check Digit Verification of cas no

The CAS Registry Mumber 82751-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,5 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 82751-25:
(7*8)+(6*2)+(5*7)+(4*5)+(3*1)+(2*2)+(1*5)=135
135 % 10 = 5
So 82751-25-5 is a valid CAS Registry Number.

A Convenient Method for Preparation of 2-(Methylthio)alkanoic Acids and Their Related Compounds Using the Carbanions of Substituted Malonic Esters

Ogura, Katasuyuki,Itoh, Hiroshi,Morita, Toshio,Sanada, Kunio,Iida, Hirotada

, p. 1216 - 1220 (2007/10/02)

Starting from alkyl- or aryl-substituted malonic esters prepared by various methods, 2-(methylthio)alkanoic acids are synthesized by successive treatment with sodium ethoxide and with S-methyl methanethiosulfonate, followed by alkaline hydrolysis which causes concurrent decarboxylation.Production of 2-(phenylthio)alkanoic acids is also achieved in a similar manner.
