Check Digit Verification of cas no

The CAS Registry Mumber 1254944-58-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,9,4 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1254944-58:
(9*1)+(8*2)+(7*5)+(6*4)+(5*9)+(4*4)+(3*4)+(2*5)+(1*8)=175
175 % 10 = 5
So 1254944-58-5 is a valid CAS Registry Number.

Synthesis and antimicrobial, acetylcholinesterase and butyrylcholinesterase inhibitory activities of novel ester and hydrazide derivatives of 3(2H)-pyridazinone

Oezcelik, Azime Berna,Goekce, Mehtap,Orhan, Ilkay,Kaynak, Fatma,Sahin, Mustafa Fethi

, p. 452 - 458 (2011/04/25)

In the current study, some novel ethyl 6-[(substituted-phenylpiperazine]- 3(2H)-pyridazinone-2-yl propionate III and 6-[(substituted-phenylpiperazine]- 3(2H)-pyridazinone-2-yl propionohydrazide IV derivatives were synthesized as acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) inhibitors. The structures of these new pyridazinone derivatives were confirmed by their IR, 1H-NMR spectra and elementary analysis. 6-Substituted-3(2H)- pyridazinone-2-yl propionate IIIa-e derivatives showed significant inhibitory activity against AChE and BChE. 6-[4-(3-Trifluoromethylphenyl)-piperazine]-3(2H) -pyridazinone-2-yl propionate IIIe has been found to be the most active compound in terms of inhibition of either AChE or BChE. Compound IIIe exhibited inhibitory activity close to that of galantamine (CAS 357-70-0) and did not show any selectivity between the two enzymes. Also the antimicrobial activities of III and IV derivatives have been evaluated. All III and IV derivatives exhibited poor antibacterial activities but moderate antifungal activities. ECV ?
