1023489-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023489-11-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,4,8 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1023489-11:
(9*1)+(8*0)+(7*2)+(6*3)+(5*4)+(4*8)+(3*9)+(2*1)+(1*1)=123
123 % 10 = 3
So 1023489-11-3 is a valid CAS Registry Number.

Pd-catalyzed β-selective direct C-H bond arylation of thiophenes with aryltrimethylsilanes
Funaki, Kenji,Sato, Tetsuo,Oi, Shuichi
, p. 6186 - 6189 (2012)
Direct arylation of thiophenes and benzothiophenes with aryltrimethylsilanes was effectively catalyzed by PdCl2(MeCN) 2 in the presence of CuCl2 as an oxidant. The reaction preferentially occurred at the β-position of both
