Check Digit Verification of cas no

The CAS Registry Mumber 109433-96-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,3 and 3 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109433-96:
(8*1)+(7*0)+(6*9)+(5*4)+(4*3)+(3*3)+(2*9)+(1*6)=127
127 % 10 = 7
So 109433-96-7 is a valid CAS Registry Number.

One-pot synthesis of 2-substituted 4-aryl-4,5-dihydro-3,1-benzoxazepines from 2-(2-Aminophenyl)-1-arylethanols via dehydration of the corresponding amides

Fukamachi, Shuhei,Konishi, Hisatoshi,Kobayashi, Kazuhiro

experimental part, p. 987 - 992 (2011/08/03)

An efficient method for the preparation of 2-substituted 4-aryl-4,5-dihydro-3,1-benzoxazepine derivatives under mild conditions has been developed. The reaction of 2-(2-aminophenyl)ethanols 1 with acid chlorides in the presence of excess Et3N in THF at room temperature gave the corresponding N-acylated intermediates 2, which were dehydrated by treatment with POCl3 to give 2-substituted 4-aryl-4,5-dihydro-3,1- benzoxazepines 3 in a one-pot reaction.
