120491-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120491-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,9 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120491-77:
(8*1)+(7*2)+(6*0)+(5*4)+(4*9)+(3*1)+(2*7)+(1*7)=102
102 % 10 = 2
So 120491-77-2 is a valid CAS Registry Number.

HALOGENATION AND NITRATION OF 2-PYRIDONES
Faidallah, Hassan M.
, p. 281 - 288 (2007/10/02)
Halogenation of the 2-pyridones 2 afforded the corresponding mono-di- or tri-halo derivative depending on the conditions of the reaction.Nitration of 2a gave the dinitro-2-pyridone 4k, while nitration of 2c yielded the 3-nitro derivative 4p.Structures were confirmed by spectral data.
