53639-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53639-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,3 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 53639-81:
(7*5)+(6*3)+(5*6)+(4*3)+(3*9)+(2*8)+(1*1)=139
139 % 10 = 9
So 53639-81-9 is a valid CAS Registry Number.

Electrochemistry of o-nitrosobenzoic acid in aqueous medium
Lamoureux, C.,Moinet, C.
, p. 599 - 603 (2007/10/02)
The electrosynthesis of 2-nitrosobenzoic acid from 2-nitrobenzoic acid, in a "redox" electrolysis cell with flowing solution through two consecutive porous working electrodes of opposite polarities, gives the monomeric form at the anode.An important part
