370555-71-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 370555-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,0,5,5 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 370555-71:
(8*3)+(7*7)+(6*0)+(5*5)+(4*5)+(3*5)+(2*7)+(1*1)=148
148 % 10 = 8
So 370555-71-8 is a valid CAS Registry Number.

Synthesis of benzo[b]thiophenes by electrophilic cyclization
Larock, Richard C,Yue, Dawei
, p. 6011 - 6013 (2001)
2,3-Disubstituted benzo[b]thiophenes are readily prepared in excellent yields under very mild reaction conditions by the Pd/Cu-catalyzed cross-coupling of commercially available o-iodothioanisole and terminal alkynes, followed by electrophilic cyclization
