Cycloocta[b]naphthalene is a polycyclic aromatic hydrocarbon (PAH) consisting of two fused benzene rings with an additional cyclooctane ring. It is a colorless solid with a molecular formula of C18H14 and a molecular weight of 230.3 g/mol. Cycloocta[b]naphthalene is characterized by its unique structure, which features a central eight-membered carbon ring fused to a naphthalene moiety. Cycloocta[b]naphthalene is known for its stability and resistance to chemical reactions, making it a subject of interest in various fields, including organic chemistry, materials science, and environmental studies. It is also found in certain coal tar products and can be synthesized through various chemical reactions. Due to its potential environmental and health impacts, research on cycloocta[b]naphthalene often focuses on its formation, detection, and mitigation strategies.
The CAS Registry Mumber 262-83-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 2 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 262-83: (5*2)+(4*6)+(3*2)+(2*8)+(1*3)=59 59 % 10 = 9 So 262-83-9 is a valid CAS Registry Number.
