143232-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143232-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,3 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143232-59:
(8*1)+(7*4)+(6*3)+(5*2)+(4*3)+(3*2)+(2*5)+(1*9)=101
101 % 10 = 1
So 143232-59-1 is a valid CAS Registry Number.

Synthesis, structures and biological activity of some 4-amino-3-cinnolinecarboxylic acid derivatives, part 1
Stanczak,Kwapiszewski,Lewgowd,Ochocki,Szadowska,Pakulska,Glowka
, p. 884 - 889 (2007/10/02)
This work describes the synthesis of 4-amino-3-cinnolinecarboxamides, which were then hydrolyzed to corresponding 4-amino-3-cinnolinecarboxylic acids. Several compounds were tested for their antibacterial and antifungal activity, and for the central nervous system effect.
