2,6-Dinitro-3-pyridinol was used as a reagent in the synthesis of pyrimidinediamine derivatives which may act as Syk protease inhibitors and can be used in drug development for treatment of diseases.
Check Digit Verification of cas no
The CAS Registry Mumber 15128-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15128-91:
(7*1)+(6*5)+(5*1)+(4*2)+(3*8)+(2*9)+(1*1)=93
93 % 10 = 3
So 15128-91-3 is a valid CAS Registry Number.

Reactivity of heterocyclic compounds in nitration. 8. Nitration of 3-hydroxypyridine and its substituted forms
Falyakhov,Gil'manov,Sharnin,Bol'shakova
, p. 830 - 832 (1998)
Nitration of 3-hydroxypyridine and its substituted forms has been studied under various conditions. It is shown that, depending on the reaction temperature and the nitrating agent, the end products of the synthesis can be 3-hydroxy-2,6-dinitropyridine or 3-hydroxy-2,4,6-trinitropyridine. The possibility of substitutional nitration of iodine derivatives of 2- and 3-hydroxypyridine is demonstrated. 1999 Kluwer Academic/Plenum Publishers.
