Check Digit Verification of cas no

The CAS Registry Mumber 161871-65-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,7 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 161871-65:
(8*1)+(7*6)+(6*1)+(5*8)+(4*7)+(3*1)+(2*6)+(1*5)=144
144 % 10 = 4
So 161871-65-4 is a valid CAS Registry Number.

A new efficient synthesis of 3-nitropyridine and substituted derivatives

Bakke, Jan M.,Ranes, Eli

, p. 281 - 283 (1997)

Pyridine and pyridine derivatives have been nitrated in the β-position by reaction with N2O5 or NO2·BF4 in MeNO2, THF or MeCN to form the N-nitropyridinium salt. This was then reacted with an aqueous solution of a nucleophile to give the β-nitro compound in moderate to good yield.

7-Azacinnolin-4(1H)-one preparation and NMR studies of tautomery

Stockmann, Vegar,Primpke, Sebastian,Fiksdahl, Anne

experimental part, p. 737 - 741 (2011/07/31)

As part of our current investigations of nitropyridines, we hereby report the preparation of a new annulated heterocycle by C-azo coupling. Thus, the azacinnoline, pyrido[3,4-c]pyridazin-4(1H)-one (38%), was prepared from 4-acetyl-3-aminopyridine via diazotization. 1H, 13C, and 15N NMR spectroscopic investigations revealed that the azacinnoline exclusively exists in the NH-keto tautomeric form in DMSO-d6, CD 3OD, and D2O.
