Check Digit Verification of cas no

The CAS Registry Mumber 347893-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,8,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 347893-45:
(8*3)+(7*4)+(6*7)+(5*8)+(4*9)+(3*3)+(2*4)+(1*5)=192
192 % 10 = 2
So 347893-45-2 is a valid CAS Registry Number.

Comparison of different heterocyclic scaffolds as substrate analog PDE5 inhibitors

Haning, Helmut,Niewoehner, Ulrich,Schenke, Thomas,Lampe, Thomas,Hillisch, Alexander,Bischoff, Erwin

, p. 3900 - 3907 (2007/10/03)

Several different heterocyclic systems were compared as PDE5 inhibitor scaffolds. In addition to the known 3H-imidazo[5,1-f][1,2,4]triazin-4-ones and pyrazolopyrimidinones, isomeric imidazo[1,5-a][1,3,5]triazin-4(3H)-ones were also shown to be potent and selective PDE inhibitor scaffolds with in vivo activity. SAR trends were elucidated for sulfonamide derivatives with generality across different scaffolds.
