1,2-Dihydrocyclohepta[fg]acenaphthylene is a polycyclic aromatic hydrocarbon (PAH) consisting of a seven-membered cycloheptane ring fused to an acenaphthylene moiety. This organic compound is characterized by its complex, planar structure with alternating double bonds and a high degree of conjugation, which contributes to its stability and potential for electronic delocalization. It is a member of a larger class of compounds known for their diverse applications in various fields, including materials science, pharmaceuticals, and as environmental pollutants. Due to its chemical structure, 1,2-dihydrocyclohepta[fg]acenaphthylene may exhibit unique physical and chemical properties, such as fluorescence or electronic conductivity, which can be harnessed for specific applications. However, like other PAHs, it may also have potential health and environmental concerns due to its persistence and potential toxicity.

518-03-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 518-03-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 8 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 518-03:
(5*5)+(4*1)+(3*8)+(2*0)+(1*3)=56
56 % 10 = 6
So 518-03-6 is a valid CAS Registry Number.

Structure and Reactivity of Polycyclic Ion Pairs

Becker, Bernd Ch.,Huber, Walter,Schnieders, Christoph,Muellen, Klaus

, p. 1573 - 1594 (2007/10/02)

A series of polycyclic ?-systems 1-5 which have in common a naphthalene moiety are reduced by alkali metals: via the intermediate radical anions the corresponding dianion salts and a tetraanion salt of 1 are obtained.The structures of the ion pairs are elucidated by spectroscopic methods.The charge distribution depends on the topology of the ?-systems and on the polarizing counterions.Knowledge of the charge distribution allows to rationalize the reactions of the dianions with electrophiles.
