19359-64-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19359-64-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19359-64:
(7*1)+(6*9)+(5*3)+(4*5)+(3*9)+(2*6)+(1*4)=139
139 % 10 = 9
So 19359-64-9 is a valid CAS Registry Number.

On the Amination of Pyrimido1,2,4-triazines in Liquid Ammonia
Brouwer, A. C.,Plas, H. C. van der
, p. 1657 - 1660 (2007/10/02)
When dissolved in liquid ammonia 5-chloro-1,2-dihydropyrimido-1,2,4-triazine (1) and 5-methoxypyrimido-1,2,4-triazine (4) quickly convert into 5-aminopyrimido-1,2,4-triazine (2).When 2 is kept in liquid ammonia containing an excess of potassium permanganate, 3,5-diaminopyrimido-1,2,4-triazine (5) is formed.
