Check Digit Verification of cas no
The CAS Registry Mumber 38965-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,6 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 38965-27:
(7*3)+(6*8)+(5*9)+(4*6)+(3*5)+(2*2)+(1*7)=164
164 % 10 = 4
So 38965-27-4 is a valid CAS Registry Number.

Esterification of Carboxylic Acids with Alcohols Using Benzenesulphonyl and Methanesulphonyl Chlorides

The role of benzene- and methane-sulphonyl chlorides as coupling agents in the esterification of carboxylic acids with alcohols has been investigated.Hindered tertiary alcohols require initial conversion of the acid to the mixed acid-anhydride with benzenesulphonyl chloride.It is necessary to adjust molar ratios for esterification with secondary alcohols so that the intermediate formed is the symmetrical acid anhydride, since mixed acid-anhydrides also give the sulphonates of the alcohols wihich are difficult to separate from the esters.
