Check Digit Verification of cas no
The CAS Registry Mumber 80567-67-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,6 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80567-67:
(7*8)+(6*0)+(5*5)+(4*6)+(3*7)+(2*6)+(1*7)=145
145 % 10 = 5
So 80567-67-5 is a valid CAS Registry Number.

supporting information; experimental part, p. 2511 - 2513 (2012/06/16)
A copper-catalyzed procedure was developed for assembling benzothiazolones from ethyl 2-iodophenylcarbamates and sodium sulfide. A number of functional groups, such as methoxy, acyl, amide, carboxylate, trifluoromethyl, fluoro, and chloro, were tolerated under these conditions, providing benzothiazolones in good yields.
