7619-71-8 Usage
General Description
7,12-diphenylbenzo[k]fluoranthene is a polycyclic aromatic hydrocarbon (PAH) used in research as a model compound for studying the toxic effects of PAHs. It is a highly carcinogenic substance and is a byproduct of incomplete combustion of organic materials, such as fossil fuels and biomass. 7,12-diphenylbenzo[k]fluoranthene is a known environmental pollutant and has been detected in air, water, and soil samples. Exposure to this compound has been linked to a range of adverse health effects, including respiratory issues, cardiovascular problems, and an increased risk of cancer. It is important to limit exposure to 7,12-diphenylbenzo[k]fluoranthene and to implement measures to reduce its production and release into the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 7619-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,1 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7619-71:
(6*7)+(5*6)+(4*1)+(3*9)+(2*7)+(1*1)=118
118 % 10 = 8
So 7619-71-8 is a valid CAS Registry Number.

From branched hydrocarbon propellers to C3-symmetric graphite disks

Branched hydrocarbon propellers (9 and 12) were prepared by stepwise palladium-catalyzed Hagihara-Sonogashira coupling reactions and Diels-Alder cycloadditions and submitted to oxidative cyclodehydrogenation by FeCl 3 to afford two new giant graphite disks 2 and 3 with 3-fold symmetry in high yield. One of the precursors, the polyphenylene dendrimer 9 containing 150 carbon atoms, was crystallographically characterized. The poorly soluble graphite disks were characterized by isotope-resolved MALDI-TOF mass spectroscopy, and their electronic and vibrational properties were investigated by solid-state UV-vis and Raman spectroscopy. The effect of molecular size and geometry on their properties was discussed. The molecule 2 represents the largest, 3-fold-symmetric all-benzenoid graphite disk, and the five-membered rings in molecule 3 open the opportunity to synthesize large bowl-shaped PAHs.
