Check Digit Verification of cas no

The CAS Registry Mumber 99147-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,4 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99147-13:
(7*9)+(6*9)+(5*1)+(4*4)+(3*7)+(2*1)+(1*3)=164
164 % 10 = 4
So 99147-13-4 is a valid CAS Registry Number.

Functionalization of carboxylic anhydrides at α-carbon with hypervalent iodine reagents: One-pot conversion of anhydrides to 2-sulfonyloxycarboxylate esters

Goff, Jeffrey M.,Justik, Michael W.,Koser, Gerald F.

, p. 5597 - 5599 (2001)

The treatment of carboxylic anhydrides with iodine(III) sulfonate reagents at ca. 100°C and esterification of the reaction mixtures with MeOH/TsOH·H2O affords 2-sulfonyloxycarboxylate esters. This is consistent with enolic behavior in the anhyd
