109571-88-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109571-88-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,7 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109571-88:
(8*1)+(7*0)+(6*9)+(5*5)+(4*7)+(3*1)+(2*8)+(1*8)=142
142 % 10 = 2
So 109571-88-2 is a valid CAS Registry Number.

IMPROVED PROCEDURE FOR THE REDUCTIVE PHENYLATION AND CYCLIZATION OF NITROARENES
Miyake, Shinji,Sasaki, Atsushi,Ohta, Toshiharu,Shudo, Koichi
, p. 5815 - 5818 (2007/10/02)
The reductive phenylation of nitroarenes was improved by using iron pentacarbonyl(IPC) as a reducing reagent.The method was applied to the synthesis of ellipticine and dibenzazocine derivatives.
