Check Digit Verification of cas no
The CAS Registry Mumber 850629-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,6,2 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 850629-65:
(8*8)+(7*5)+(6*0)+(5*6)+(4*2)+(3*9)+(2*6)+(1*5)=181
181 % 10 = 1
So 850629-65-1 is a valid CAS Registry Number.

Page/Page column 6, (2008/06/13)
A process for producing an ester includes the step of allowing a carboxylic acid to react with an alcohol, wherein an ammonium sulfonate is used as an esterification catalyst, the ammonium sulfonate being composed of an ammonium cation having a basic skeleton represented by formula (1) (wherein n represents 1 or 2) in which hydrogen atoms in the benzene rings and hydrogen atoms bonded to bridge carbon may be substituted), and a sulfonic acid anion represented by RSO 3 - (wherein R represents an arene, a perfluoroalkane having 1 to 8 carbon atoms, or a bulky alkane).
