Check Digit Verification of cas no

The CAS Registry Mumber 1196586-09-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,6,5,8 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1196586-09:
(9*1)+(8*1)+(7*9)+(6*6)+(5*5)+(4*8)+(3*6)+(2*0)+(1*9)=200
200 % 10 = 0
So 1196586-09-0 is a valid CAS Registry Number.

Unsymmetrical cruciforms

(Chemical Equation Presented) Five new, unsymmetrical 1,4-distyryl-2,5- bisphenylethynylbenzenes (cruciforms, XF) have been prepared by a sequential Horner reaction of the bisphosphonate of 2,5-diiodo-1,4-xylene with two different aromatic aldehydes. The obtained diiodide was coupled to phenylacetylene under Sonogashira conditions with (Ph3P) 2PdCl2 as catalyst. The resulting XFs carry dibutylamino, pyridyl, cyano, and diphenylamino residues on their styryl arms to give rise to donor-, acceptor-, and donoracceptor-substitutedXFs. The optical properties of theseXFswere investigated.Titration studies using trifluoroacetic acid tracked changes in the electronic structure of the XFs upon protonation. Donor XFs display a blue shift in absorption and emission upon protonation,while the pyridyl-substitutedXF displays red shift in absorption and emission upon protonation. In the case of the donor-acceptor XF carrying a pyridyl and an aminostyryl arm, the first protonation occurs either on the pyridine or on the dibutylamino arm; a red shift is seen in absorption (for the former) and a blue shift is observed in emission (for the latter). The titration studies indicate that the protonated XFs do not display kinetic photoacidity when operating either in dichloromethane or acetonitrile solutions. The trends observed for protonation were mirrored when the XFs bind to metal cations.While the binding constants of the metal cations to theXFs were lower than for that for protons, as in some cases fullmetalation of theXF could not be obtained, the results were qualitatively the same. We did not find dynamic excited-state decomplexation events in theXFs that we have investigated.TheXFs, stilbene derivatives, are different from other reported, similarly structured fluorophores as they show significant ratiometric changes in emission upon metal complexation; thus, distyrylbenzene-derived fluorophores may be, in the end, viable choices as platforms for metal ion detection.
