Check Digit Verification of cas no
The CAS Registry Mumber 113570-93-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,7 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113570-93:
(8*1)+(7*1)+(6*3)+(5*5)+(4*7)+(3*0)+(2*9)+(1*3)=107
107 % 10 = 7
So 113570-93-7 is a valid CAS Registry Number.

Photochemical Synthesis of Benzothiazoles
Paramasivam, R.,Ramakrishnan, V. T.
, p. 930 - 934 (2007/10/02)
Irradiation of o-halothioacetanilides (1a-p) affords benzothiazoles (2a-p) in general.In methanol medium, polyhalogenated thioacetanilides yield benzothiazoles with the loss of bromine atom in the 4- or 6-position of the benzothiazole.Arylation of benzothiazoles occurs in benzene medium.
