Dibenzo[hi,wx]heptacene is a polycyclic aromatic hydrocarbon (PAH) consisting of seven fused aromatic rings, with two benzene rings attached to the heptacene core. This organic compound is characterized by its complex molecular structure, which contributes to its unique chemical and physical properties. Dibenzo[hi,wx]heptacene is known for its potential applications in materials science, particularly in the development of organic semiconductors and optoelectronic devices, due to its electronic properties and stability. However, like other PAHs, it may also exhibit toxicological properties, and further research is needed to fully understand its environmental and health implications.

197-73-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 197-73-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,9 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197-73:
(5*1)+(4*9)+(3*7)+(2*7)+(1*3)=79
79 % 10 = 9
So 197-73-9 is a valid CAS Registry Number.

Modular Approach to the Synthesis of Two-Dimensional Angular Fused Acenes

Feofanov, Mikhail,Akhmetov, Vladimir,Sharapa, Dmitry I.,Amsharov, Konstantin

supporting information, p. 1698 - 1702 (2020/01/31)

Herein, we present a modular approach to pristine angularly fused planar acenes. The approach includes the Pd-catalyzed fusion of several building blocks and implements a dehydrative ?-extension (DPEX) reaction as a key step enabling facile access to diverse two-dimensional acenes. The scope was demonstrated on nine examples with up to quantitative yield.
