126336-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126336-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,3 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 126336-98:
(8*1)+(7*2)+(6*6)+(5*3)+(4*3)+(3*6)+(2*9)+(1*8)=129
129 % 10 = 9
So 126336-98-9 is a valid CAS Registry Number.

Synthesis of Aminopyridazines from Azidopyridazines and Tetrazolopyridazines
Kappe, Th.,Pfaffenschlager, A.,Stadlbauer, W.
, p. 666 - 671 (2007/10/02)
Azidopyridazines 3, 4, 24 and tetrazolopyridazines 10, 13, 28 can be converted to the corresponding aminopyridazines, by reaction with triphenylphosphine via phosphazenes and subsequent hydrolysis (Staudinger reaction).
