59591-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59591-40-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,5,9 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 59591-40:
(7*5)+(6*9)+(5*5)+(4*9)+(3*1)+(2*4)+(1*0)=161
161 % 10 = 1
So 59591-40-1 is a valid CAS Registry Number.

Synthesis of 3,5-diphenyl-4(1H)-pyridazinones
-
, (2008/06/13)
A series of 3,5-diphenyl-4(1H)-pyridazinones are synthesized by a two-step process, both steps of which are new. In the first step, a phenylglyoxyloyl halide is reacted with a styrylamine in the presence of a base to form a 1-amino-2,4-diphenyl-1-buten-3,
