98570-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 98570-53-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,7 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98570-53:
(7*9)+(6*8)+(5*5)+(4*7)+(3*0)+(2*5)+(1*3)=177
177 % 10 = 7
So 98570-53-7 is a valid CAS Registry Number.

Preparation and Spectroscopic Characterization of Cyclopentadicoronene

Zander, M.,Friedrichsen, W.

, p. 1314 - 1318 (2007/10/02)

The non-alternant hydrocarbon cyclopentadicoronene (3) has been prepared by aluminium chloride catalyzed dimerization of coronene (1).The UV/VIS absorption spectrum, fluorescence spectrum and fluorescence quantum yield of 3 is reported and compared with that of the alternant isomer benzodicoronene (2).Relationships observed in the UV/VIS absorption spectra of alternant and non-alternant polycyclic aromatic hydrocarbons and preliminary theoretical investigations (PMO calculations) on two model systems (C, E) are also reported. Key words: Dicoronylene isomers; UV/VIS absorption spectra; fluorescence spectra.
