Check Digit Verification of cas no

The CAS Registry Mumber 1246616-95-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,6,1 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1246616-95:
(9*1)+(8*2)+(7*4)+(6*6)+(5*6)+(4*1)+(3*6)+(2*9)+(1*5)=164
164 % 10 = 4
So 1246616-95-4 is a valid CAS Registry Number.

The medicinal chemistry and structure-activity relationships (SAR) for a novel series of carbamoyl pyridone bicycle (CAB) compounds as influenza Cap-dependent endonuclease (CEN) inhibitors are disclosed. Substituent effects were evaluated at the C (N)-1, N-3, and C-7 positions of the CAB ring system using a docking study. Submicromolar EC50 values were achieved in the cellular assay with C-7-unsubstituted CAB which possessed a benzhydryl group on either the C-1 or the N-1 position. An N-3 substituent was found to be critical for the plasma protein binding effect in vitro, and the CAB-N analogue 2v exhibited reasonable total clearance (CLtot). More importantly, compound 2v displayed significant efficacy in a mouse model infected with influenza viruses.
