Check Digit Verification of cas no

The CAS Registry Mumber 144242-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,4 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144242-89:
(8*1)+(7*4)+(6*4)+(5*2)+(4*4)+(3*2)+(2*8)+(1*9)=117
117 % 10 = 7
So 144242-89-7 is a valid CAS Registry Number.

Synthesis and Biological Activity of 4-(Diphenylmethyl)-α--1-piperazineethanol and Related Compounds

Sircar, Ila,Haleen, Steve J.,Burke, Sandra E.,Barth, Hubert

, p. 4442 - 4449 (2007/10/02)

A series of 4-(diphenylmethyl)-α--1-piperazineethanol and closely related compounds was synthesised and evaluated for cardiac and vascular activity in isolated perfused rat and guinea pig hearts.Compound 1 produced greater inotropic effects in rat hearts than in guinea pig hearts, a phenomenon which was also observed with the prototype agent DPI 201-106.Compound 15 produced an inotropic effect with one-tenth the potency of compound 1.Both compounds 1 and 15 demonstrated direct inotropic and vasodilatory effects when administered iv in anesthetized dogs, although the vasodilatory activity was more pronounced with compound 15 than 1 and DPI compound.Compound 1 lacks the CN moiety which is a key structural requirement in DPI for positive inotropic activity.The synthesis, in vitro, and in vivo evaluations of these agents, and comparative data with DPI-201-106 (compound 17) are reported.
