Check Digit Verification of cas no

The CAS Registry Mumber 437998-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,7,9,9 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 437998-39:
(8*4)+(7*3)+(6*7)+(5*9)+(4*9)+(3*8)+(2*3)+(1*9)=215
215 % 10 = 5
So 437998-39-5 is a valid CAS Registry Number.

A novel class of quinazolinone derivatives as potent poly(ADP-ribose) polymerase-1 (PARP-1) inhibitors has been discovered. Key to success was application of a rational discovery strategy involving structure-based design, combinatorial chemistry, and classical SAR for improvement of potency and bioavailability. The new inhibitors were shown to bind to the nicotinamide-ribose binding site (NI site) and the adenosine-ribose binding site (AD site) of NAD+.
