170960-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 170960-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,9,6 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 170960-90:
(8*1)+(7*7)+(6*0)+(5*9)+(4*6)+(3*0)+(2*9)+(1*0)=144
144 % 10 = 4
So 170960-90-4 is a valid CAS Registry Number.

A novel approach to the synthesis of 1-substituted-3,6-diaryl-imidazo[1,5-b]pyridazines
Zhaou,Zhang
, p. 3271 - 3286 (2007/10/03)
A simple and efficient procedure for the preparation of a new type of 1-substituted-3,6-diaryl-imidazo[1,5-b]pyridazines was described. This synthesis was carried out by the following three steps: Aryl methyl ketone 3 was condensed with 1-amino-2-substitu
