Check Digit Verification of cas no

The CAS Registry Mumber 84539-19-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,5,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 84539-19:
(7*8)+(6*4)+(5*5)+(4*3)+(3*9)+(2*1)+(1*9)=155
155 % 10 = 5
So 84539-19-5 is a valid CAS Registry Number.

Synthesis of some pyrimidine N-oxides

Jovanovic, Misa V.

, p. 1176 - 1180 (2007/10/02)

Various monosubstitudes pyrimidines and methylpyrimidines were N-oxidized with a number of different peracids.In general, they are more susceptible to side reactions accompanying N-oxidation (i.e., decomposition, annular carbon oxidation, ring opening) than other ?-deficient diazine and triazine analogs.Unsymmetrical pyrimidines, which can potentially yield two isomeric products, were N-oxidized preferentially at the site para to strong electron-donating substituents.Weaker ringactivating groups, such as methyl, are mainly ortho directing and only aid in the N-oxidation of pyrimidine nuclei having ortho/para-directing substituents.
