Check Digit Verification of cas no

The CAS Registry Mumber 17721-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,7,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17721-91:
(7*1)+(6*7)+(5*7)+(4*2)+(3*1)+(2*9)+(1*1)=114
114 % 10 = 4
So 17721-91-4 is a valid CAS Registry Number.

The Chemistry of Phthalide-3-carboxylic Acid. II. Decarboxylation of Salts in the Presence of Aldehydes

Dibbens, Justin A.,Prager, Rolf H.,Schiesser, Carl H.,Wells, Andrew J.

, p. 913 - 920 (2007/10/02)

Salts of phthalide-3-carboxylic acid decarboxylate in the presence of aromatic aldehydes to give mixtures of the 3-(arylhydroxymethyl)phthalide (2) and the 2-aryl-3-hydroxyindenone (3).The former may be obtained exclusively in the presence of the weak proton donor, triethyl(2-phenylethyl)ammonium chloride, and the latter in the presence of crown ethers or after longer reaction times.A study of the effect of different cations allows a mechanism to be deduced.
