83443-01-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83443-01-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83443-01:
(7*8)+(6*3)+(5*4)+(4*4)+(3*3)+(2*0)+(1*1)=120
120 % 10 = 0
So 83443-01-0 is a valid CAS Registry Number.

The Synthesis and Reactions of 4H-Tetrazolobenzothiazines
Kay, David P.,Kennewell, Peter D.,Westwood, Robert
, p. 1879 - 1884 (2007/10/02)
The synthesis of 4H-tetrazolobenzothiazines via an intramolecular dipolar addition reaction of 2-(2-azidophenylthio)acetonitrile is described.The methylene protons of the thiazine ring were found to be sufficiently acidic to be readily functio
