347187-82-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 347187-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,1,8 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 347187-82:
(8*3)+(7*4)+(6*7)+(5*1)+(4*8)+(3*7)+(2*8)+(1*2)=170
170 % 10 = 0
So 347187-82-0 is a valid CAS Registry Number.

, p. 150 - 151 (2007/10/03)
Reaction of 2-aminobenzethiol with oxalyl chloride in presence of triethylamine in benzene gives 1,4-benzothiazine-2,3-dione (1) which when N-alkylated with chloroacetone forms N-(2′-propanonyl)-1,4-benzothiazine-2,3-dione (2). Base catalysed intramolecul
