Check Digit Verification of cas no
The CAS Registry Mumber 33245-29-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,2,4 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33245-29:
(7*3)+(6*3)+(5*2)+(4*4)+(3*5)+(2*2)+(1*9)=93
93 % 10 = 3
So 33245-29-3 is a valid CAS Registry Number.

Syntheses with Aromatic Nitramines. IX. Halogenation of 2- and 4-Nitraminopyridines
Brzozka, L.,Baran, W.,Kraus, W.,Tomasik, P.
, p. 605 - 611 (2007/10/02)
Isomeric 2- and 4-nitraminopyridines (free acids and anions) were subjected to halogenation (iodination, bromination and chlorination).The iodination of nitraminopyridine anions failed, and the bromination and chlorination led selectively to 5-monohalogenated products independently of whether free acids or anions of nitraminopyridines were reacted.Key words: nitraminopyridines, halogenation
