Check Digit Verification of cas no
The CAS Registry Mumber 881997-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,9,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 881997-21:
(8*8)+(7*8)+(6*1)+(5*9)+(4*9)+(3*7)+(2*2)+(1*1)=233
233 % 10 = 3
So 881997-21-3 is a valid CAS Registry Number.

A series of 4-oxo-4H-pyrido[1,2-a]pyrimidine derivatives, derivatized at the 2-position with carbon-linked substituents, were synthesized and evaluated for their ability to potentiate the activity of the fluoroquinolone levofloxacin (LVFX) and the anti-pseudomonas β-lactam aztreonam (AZT) in Pseudomonas aeruginosa. Palladium-catalyzed cross-coupling methods were applied for the incorporation of aliphatic and aromatic substituents.
