104720-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104720-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,2 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 104720-62:
(8*1)+(7*0)+(6*4)+(5*7)+(4*2)+(3*0)+(2*6)+(1*2)=89
89 % 10 = 9
So 104720-62-9 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 (1985)
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.
