Check Digit Verification of cas no
The CAS Registry Mumber 135513-86-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,5,1 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 135513-86:
(8*1)+(7*3)+(6*5)+(5*5)+(4*1)+(3*3)+(2*8)+(1*6)=119
119 % 10 = 9
So 135513-86-9 is a valid CAS Registry Number.

Oxidative Methylamination of Some Nitropyridines
Szpakiewicz, Barbara,Wozniak, Marian
, p. 75 - 78 (2007/10/03)
2-, 3-, 4-Nitropyridine (1a, i, j) and some simple derivatives of 3-nitropyridine (1b-h) undergo dehydromethylamination in a solution of potassium permanganate in liquid methylamine. In the case of 2- and 6-chloro and 6-methoxy derivatives of 3-nitropyridine (1b-d) dechloro- or demethoxy-methylamination occurs as well.
Regioselectivity of the Amination of Some 3-Nitropyridines by Liquid Ammonia / Potassium Permanganate
Wozniak, Marian,Baranski, Andrzej,Szpakiewicz, Barbara
, p. 875 - 878 (2007/10/02)
3-Nitropyridine and some of its derivatives are aminated in a liquid ammonia solution of potassium permanganate to the corresponding 2- and (or) 4- and (or) 6-amino compounds.Quantumchemical calculations for a few 3-nitropyridines suggest that the experimentally observed regioselectivity of the amination is controlled by Coulombic interaction. --- Key Words: Amination / Nitropyridines / Reactivity indices / Calculations, MNDO
