Check Digit Verification of cas no
The CAS Registry Mumber 77086-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,8 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77086-78:
(7*7)+(6*7)+(5*0)+(4*8)+(3*6)+(2*7)+(1*8)=163
163 % 10 = 3
So 77086-78-3 is a valid CAS Registry Number.

SYNTHESIS OF HETEROCYCLES : SYNTHESIS OF 4H-1,4-BENZOTHIAZINES
Soni, R. P.,Jain, M. L.
, p. 3795 - 3796 (1980)
A new synthesis of fluorinated 4H-1,4-benzothiazines is being reported for the first time, obtained by condensing O-aminobenzenethiol with fluorinated β-diketones.An oxidative cyclisation mechanism, involving an intermolecular nucleophilic attack in an intermediate anamine system is suggested.
