Check Digit Verification of cas no

The CAS Registry Mumber 80904-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,0 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80904-34:
(7*8)+(6*0)+(5*9)+(4*0)+(3*4)+(2*3)+(1*4)=123
123 % 10 = 3
So 80904-34-3 is a valid CAS Registry Number.

Pyrazine-1,4-dioxides fused to heterocycles. II comm.: Synthesis and antibacterial activity of substituted pyrido[2,3-b]pyrazine-1,4-dioxides

Binder,Georgopoulos,Noe,Nussbaumer,Prager,Turnowsky

, p. 10 - 14 (2007/10/02)

The position selective synthesis of substituted pyrido[2,3-b]-pyrazine-1,4-dioxides is reported. Compound 3g was subjected to a series of screening-tests for antibacterial activity and compared to therapeutical standards. The range of antibacterial activity mainly comprises enterobacteriaceae, above all E, coli, Klebsiella, Proteus and Shigella strains. Activity against grampositive organisms and Serratia is much weaker and completely lacking with Pseudomonas. Therapeutic activity in septicaemic infections of the mouse is very good, especially in the case of E. coli infection with an ED50 of 13 mg/kg mouse for s.c. application. With p.o. application 3g shows activity comparable to nalidixic acid and nitrofurantoin in the experimental acute pyelonephritis in the mouse. The activity of 3g, however, is clearly inferior to that of gentamicin.
