147090-24-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147090-24-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,0,9 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 147090-24:
(8*1)+(7*4)+(6*7)+(5*0)+(4*9)+(3*0)+(2*2)+(1*4)=122
122 % 10 = 2
So 147090-24-2 is a valid CAS Registry Number.

, p. 39 - 43 (2007/10/02)
The coupling of 1-amino-2,6,6-tricyanocyclohexadiene derivatives 1-3 with a variety of aryldiazonium salts produces the hydrazones 5-7 which in the presence of weak base in ethanol at elevated temperature furnish 2-aryl-4-cyanopyridazin-3(2H)-ones 8-10. I
