1606142-51-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1606142-51-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,6,1,4 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1606142-51:
(9*1)+(8*6)+(7*0)+(6*6)+(5*1)+(4*4)+(3*2)+(2*5)+(1*1)=131
131 % 10 = 1
So 1606142-51-1 is a valid CAS Registry Number.

This article presents a synthetic method and reaction mechanism of the 1,5-benzothiazepines and 1,5-benzodiazepines derivatives. In this research, 36 thiazepines and diazepines (mostly new) with a new method have been prepared and their structures have been characterized by spectroscopic methods. Crystal structures of a new thiazepine and diazepine (seven-membered rings) have also been determined and compared with thiazine (six-membered ring). In this method, N-methylimidazolium nitrate [Hmim][NO3] has been used as a catalyst that acts as an environmental friendly system.
