Check Digit Verification of cas no

The CAS Registry Mumber 1256815-36-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,8,1 and 5 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1256815-36:
(9*1)+(8*2)+(7*5)+(6*6)+(5*8)+(4*1)+(3*5)+(2*3)+(1*6)=167
167 % 10 = 7
So 1256815-36-7 is a valid CAS Registry Number.

Synthesis, biological assay in vitro and molecular docking studies of new imidazopyrazinone derivatives as potential dipeptidyl peptidase IV inhibitors

experimental part, p. 4953 - 4962 (2010/11/18)

A series of novel imidazopyrazinone derivatives were synthesized and evaluated with regard to their ability to inhibit dipeptidyl peptidase IV (DPP-IV) in vitro. Of these compounds (2R)-4-oxo-4-[2-(3-carbamoylbenzyl)- hexahydro-3-oxoimidazo [1,5-a]pyrazin-7(8H)-yl]-1-(2,4,5-trifluorophenyl)butan- 2-amine fumaric acid (17h, IC50 = 78 nM) was shown to effectively inhibit the activity of the dipeptidyl peptidase IV enzyme. Molecular docking studies were also performed to illustrate the binding mode of compounds 15c and 17h. Favorable interactions were identified from the binding of inhibitor 15c with DPP-IV. By analogy to the binding mode of compound 15c, it seems that the introduction of a substituted benzyl moiety onto the imidazopyrazinone could remarkably improve the inhibitory activity of compound 17h.
