Naphtho[1,2-g]chrysene is a polycyclic aromatic hydrocarbon (PAH) consisting of a naphthalene ring fused to a chrysene molecule. It is a large, planar molecule with a complex structure, containing multiple fused benzene rings. naphtho[1,2-g]chrysene is known for its potential environmental and health impacts, as PAHs are often found in polluted air, water, and soil, and can be released from various sources such as combustion processes and industrial activities. Due to its chemical stability and resistance to degradation, naphtho[1,2-g]chrysene can persist in the environment and pose risks to both human health and ecosystems. It is classified as a potential carcinogen, and exposure to high levels can lead to various health issues, including respiratory problems and an increased risk of cancer.

Check Digit Verification of cas no

The CAS Registry Mumber 191-67-3 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 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 191-67:
(5*1)+(4*9)+(3*1)+(2*6)+(1*7)=63
63 % 10 = 3
So 191-67-3 is a valid CAS Registry Number.

Oxidative Intramolecular C-C Bond Formation Reactions of 1,2-Diarylbenzenes: Syntheses of Highly Conjugated Double-Bridged Polycyclic Aromatic Hydrocarbons

Islam, Md. Rafikul,Nishinaga, Tohru,Hirabayashi, Kazunori,Shimizu, Toshio,Sugiura, Ken-Ichi

, p. 383 - 392 (2021/10/05)

Oxidation reactions of 1,2-diarylbenzenes induce intramolecular C-C bond formation. The substrates studied were prepared by the stepwise Suzuki-Miyaura coupling reaction that introduced 2-naphthyl, 2-anthranyl, and 2-pyrenyl groups on the ortho -positions
