Check Digit Verification of cas no

The CAS Registry Mumber 727665-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,7,6,6 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 727665-94:
(8*7)+(7*2)+(6*7)+(5*6)+(4*6)+(3*5)+(2*9)+(1*4)=203
203 % 10 = 3
So 727665-94-3 is a valid CAS Registry Number.

Synthesis of dibenzo[b,f][1,4]oxazepin-11(10H)-ones from 2-nitrobenzoic acids

Samet,Kislyi,Marshalkin,Semenov

, p. 549 - 553 (2006)

Base-catalyzed intramolecular nucleophilic substitution for the 2-nitro group in 2-hydroxyanilides of 2-nitrobenzoic acids gave dibenzo[b,f][1,4] oxazepin-11(10H)-ones. In particular, 3-nitrodibenzo[b, f][1,4]oxazepin-11(10H)- one was obtained from N-(2-hydroxyphenyl)-2,4-dinitrobenzamide. The nitro group in the product could also be replaced under the action of O- and S-nucleophiles.
