161373-42-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161373-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,3,7 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161373-42:
(8*1)+(7*6)+(6*1)+(5*3)+(4*7)+(3*3)+(2*4)+(1*2)=118
118 % 10 = 8
So 161373-42-8 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.
