Check Digit Verification of cas no
The CAS Registry Mumber 152942-00-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,9,4 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 152942-00:
(8*1)+(7*5)+(6*2)+(5*9)+(4*4)+(3*2)+(2*0)+(1*0)=122
122 % 10 = 2
So 152942-00-2 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).
