17647-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 17647-71-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,4 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17647-71:
(7*1)+(6*7)+(5*6)+(4*4)+(3*7)+(2*7)+(1*1)=131
131 % 10 = 1
So 17647-71-1 is a valid CAS Registry Number.

Synthesis of furazane conjugated new heterocycles
Beaudegnies, Renaud,Wendeborn, Sebastian
, p. 2417 - 2424 (2007/10/03)
An improved route for the synthesis of 3-(4-aminofurazane-3-yl)-1,2,4-oxadiazole heterocycles using micro-wave irradiation is reported. The preparation of novel 4-(thiazol-4-yl)furazan-3-ylamine, 4-(pyrimidin-4-yl)furazan-3-ylamine and, 4-(pyrazolidin-3-yl)furazan-3-ylamine heterocycles are described.
