Check Digit Verification of cas no
The CAS Registry Mumber 56181-38-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,8 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 56181-38:
(7*5)+(6*6)+(5*1)+(4*8)+(3*1)+(2*3)+(1*8)=125
125 % 10 = 5
So 56181-38-5 is a valid CAS Registry Number.

Bromination of Some Pyridine and Diazine N-Oxides
Paudler, William W.,Jovanovic, Misa V.
, p. 1064 - 1069 (2007/10/02)
Selected monosubstituted pyridines, pyrazines, pyrimidines, and their N-oxides, having an electron-donating substituent, were successfully brominated under very mild conditions.The N-oxide function itself is not sufficient to cause these ?-deficient systems to undergo electrophilic aromatic halogenation.Only strongly electron-donating substituents (amino groups) activate the heterocyclic nucleus toward bromination.These substituents direct the electrophilic substitution ortho/para to them with or without the N-oxide group present.Pyridine and diazines with moderately activating substituents such as alkoxy groups are brominated only when their ortho/para activation is augmented by the activation of the N-oxide funtion.Failure to brominate 5-methoxypyrimidine 1-oxide may well reflect the greater ? deficiency of the pyrimidine ring.
