Check Digit Verification of cas no
The CAS Registry Mumber 6287-82-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,8 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6287-82:
(6*6)+(5*2)+(4*8)+(3*7)+(2*8)+(1*2)=117
117 % 10 = 7
So 6287-82-7 is a valid CAS Registry Number.

Synthesis of 2,3-disubstituted benzo[b]thiophenes via palladium-catalyzed coupling anphilic cyclization of terminal acetylenes
Yue, Dawei,Larock, Richard C.
, p. 1905 - 1909 (2007/10/03)
2,3-Disubstituted benzo[b]thiophenes have been prepared in excellent yields via coupling of terminal acetylenes with commercially available o-iodothioanisole in the presence of a palladium catalyst and subsequent electrophilic cyclization of the resulting
