Check Digit Verification of cas no
The CAS Registry Mumber 90004-07-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,0 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90004-07:
(7*9)+(6*0)+(5*0)+(4*0)+(3*4)+(2*0)+(1*7)=82
82 % 10 = 2
So 90004-07-2 is a valid CAS Registry Number.

Cyclotransformation in the series of fused 5-nitropyridin-2(1H)-ones
Smolyar,Yutilov
, p. 274 - 281 (2008)
Reactions with excess hydrazine hydrate of 5-nitropyridin-2(1H)-ones fused with benzene, pyridine, and 1,2,3-triazole rings led to a cyclotransformation of the 5-nitro-2-oxopyridine fragment into the 6-methyl-3-oxopyridazine structure. This cyclotransformation is of general character; a probable mechanism of the process is suggested. Details of the assumed mechanism were experimentally confirmed on model compounds.
