81981-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81981-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,8 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81981-36:
(7*8)+(6*1)+(5*9)+(4*8)+(3*1)+(2*3)+(1*6)=154
154 % 10 = 4
So 81981-36-4 is a valid CAS Registry Number.

N-OXIDATION VERSUS EPOXIDATION IN POLYCYCLIC AZAARENES
Engelhardt, Ulrich,Schaefer-Ridder, Maria
, p. 4687 - 4690 (2007/10/02)
Oxidation of the 3,4-dihydrodiols of benzacridines yielded preferably N-oxides in the series and in the series the bay region epoxide thus suggesting different metabolic pathways for noncarcinogenic and carcinogenic azaarenes.
