Check Digit Verification of cas no
The CAS Registry Mumber 104753-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 104753-89:
(8*1)+(7*0)+(6*4)+(5*7)+(4*5)+(3*3)+(2*8)+(1*9)=121
121 % 10 = 1
So 104753-89-1 is a valid CAS Registry Number.

Process for the preparation of 2-nitro-3-aminopyridine, and the intermediates which are formed in the reaction
-
, (2008/06/13)
2-Nitro-3-aminopyridine is prepared by (a) reacting 3-aminopyridine with phosgen COCl2 or urea H2 NCONH2 to give N,N'-di-(3-pyridyl)-urea, (b) nitrating and N,N'-di-(3-pyridyl)-urea with nitric acid or with a mixture of nitric acid and sulfuric acid to give N,N'-di-(2-nitor-3-pyridyl)-urea, and (c) hydrolyzing said N,N'-di-(2-nitro-3-pyridyl)-urea to give 2-nitro-3-amino-pyridine. N,N'-di-(3-pyridyl)-urea and N,N'-di-(2-nitro-3-pyridyl)-urea, which are formed in the course of the reaction as intermediates are new compounds. The end product of the process, 2-nitro-3-aminonpyridine, is an intermediate in various specialized fields.
