Check Digit Verification of cas no
The CAS Registry Mumber 4093-89-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4093-89:
(6*4)+(5*0)+(4*9)+(3*3)+(2*8)+(1*9)=94
94 % 10 = 4
So 4093-89-4 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.
