Check Digit Verification of cas no
The CAS Registry Mumber 84487-11-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,4,8 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 84487-11:
(7*8)+(6*4)+(5*4)+(4*8)+(3*7)+(2*1)+(1*1)=156
156 % 10 = 6
So 84487-11-6 is a valid CAS Registry Number.

Kinetic Studies of the Mechanism of the Nitraminopyridine Rearrangement
Deady, Leslie W.,Korytsky, Olga L.
, p. 2035 - 2040 (2007/10/02)
Rate data are reported for the rearrangement, in 92percent sulfuric acid at 30 deg C, of a series of 4-X-2-nitraminopyridines (X=H, Me, Br, Cl, MeO, CO2H) and of 4-methyl-2-nitramino(3-D)-pyridine.Values of pKa for second protonation of the corresponding pyridin-2-amines were also measured and rate constants for nitration of the monoprotonated pyridinamines were thereby calculated.The results suggest that the rate-determining step occurs prior to formation of the appropriate 3- and 5-nitro ? complexes.The nature of this step is not clear, however, and a key role for the nitramine itself is not proven by the current evidence
