37139-10-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 37139-10-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,1,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 37139-10:
(7*3)+(6*7)+(5*1)+(4*3)+(3*9)+(2*1)+(1*0)=109
109 % 10 = 9
So 37139-10-9 is a valid CAS Registry Number.

Organic Azides in Heterocyclic Synthesis, 14. Synthesis of 3,6-Diaminopyridazine from 6-Azidotetrazolopyridazine

Deeb, Ali,Sterk, Heinz,Kappe, Thomas

, p. 1225 - 1227 (2007/10/02)

6-Azidotetrazolopyridazine ("3,6-Diazidopyridazine", 1) reacts at ambient temperature with phosphanes or phosphites 2a - c to yield the phosphazenes 3a - c.In contrast to literature reports, the tetrazolopyridazines 1, and 3a,b react with phosphanes to yield 3,6-bis(phosphoranylideneamino)pyridazines 4; however, the required temperature is rather high (180 deg C).The use of phosphites instead of phosphanes leads to "Michaelis-Arbuzov-type" rearrangements; thus, 3a reacts in boiling 2d to afford 6, and heating of the trimethoxyphosphazene 3c in refluxing 1,2-dichlorobenzene yields the methylamino derivative 7.Key words: Staudinger reaction / Phosphanes / Phosphites / Phosphazenes / Amidophosphonates
