Check Digit Verification of cas no
The CAS Registry Mumber 804476-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,4,4,7 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 804476-57:
(8*8)+(7*0)+(6*4)+(5*4)+(4*7)+(3*6)+(2*5)+(1*7)=171
171 % 10 = 1
So 804476-57-1 is a valid CAS Registry Number.

Synthesis of benzothiazoles via ipso substitution of ortho- methoxythiobenzamides
Downer, Nadale K.,Jackson, Yvette A.
, p. 3039 - 3043 (2004)
An efficient route to the synthesis of benzothiazoles from orthoo-methoxythiobenzamides via the ipso substitution of an aromatic methoxy group is presented, and the mechanism of the Jacobson synthesis of benzothiazoles is further investigated.
