7191-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7191-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7191-81:
(6*7)+(5*1)+(4*9)+(3*1)+(2*8)+(1*1)=103
103 % 10 = 3
So 7191-81-3 is a valid CAS Registry Number.

Microwave-assisted synthesis of substituted dibenzo[b,f][1,4]thiazepines, dibenzo[b,f][1,4]oxazepines, benzothiazoles, and benzimidazoles

Lin, Yu-Chin,Li, Ni-Ching,Cherng, Yie-Jia

, p. 808 - 814 (2014/06/10)

A highly efficient synthesis for possessing 7-membered rings with two heteroatoms is described, using efficient microwave-assisted one-pot method to synthesize (substituted) dibenzo[b,f][1,4]thiazepines [1] and dibenzo[b,f][1,4]oxazepines [2] in high yields (up to 99%) by cyclocondensations of o-aminothiophenol or o-aminophenol with o-halobenzaldehydes, o-fluoroacetophenone, and o-fluorobenzophenone. In the absence of base, o-aminothiophenol reacted with o-halobenzaldehydes to afford benzothiazoles.
