Check Digit Verification of cas no

The CAS Registry Mumber 117663-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,6 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117663-72:
(8*1)+(7*1)+(6*7)+(5*6)+(4*6)+(3*3)+(2*7)+(1*2)=136
136 % 10 = 6
So 117663-72-6 is a valid CAS Registry Number.

3H-azepines and related systems. Part 4. Preparation of 3 H-azepin-2-ones and 6H-azepino[2,1-b]quinazolin-12-ones by photo-induced ring expansions of aryl azides

Lamara, Kaddour,Smalley, Robert K.

, p. 2277 - 2290 (1991)

Photolysis of a series of p-substituted phenyl azides (p-X-C6H4N3; X= CO2Me, CO2Et, CN, CF3, SO2NH2, CO2CHPh2, COMe, CHO, and NO2) in 1:1 (v/v) THF-water solution produces, in the majority of cases, a 5-substituted-3H-azepine-2-one. In a like manner, 3H-azepin-2-one-3-carboxylates can be prepared from 5-substituted-2-azidobenzoates, providing the 5-substituent is electron-withdrawing. 3H-Azepin-2-one mono- and di-carboxylic acids, the former in admixture with decarboxylated material, and 6H-azepino[2,1-b]quinazolin-12-ones, are obtained by irradiation of 2-azidobenzoic acid and of 5-azidoisophthalic acid, respectively. The mode of formation of the azepino-quinazolinones is discussed.
