Benzo[3,4]cyclobuta[1,2-l]phenanthrene is a polycyclic aromatic hydrocarbon (PAH) consisting of a benzene ring fused to a cyclobutane ring, which is in turn fused to a phenanthrene ring. This complex organic molecule is characterized by its unique structure, which contributes to its chemical properties and potential applications. It is a member of a larger class of PAHs, which are known for their diverse range of biological activities and environmental significance. Benzo[3,4]cyclobuta[1,2-l]phenanthrene, like other PAHs, is formed during the incomplete combustion of organic materials and can be found in various environmental settings, including air, water, and soil. Due to its persistence and potential toxicity, it is important to understand its behavior in the environment and its impact on human health.
The CAS Registry Mumber 252-23-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 252-23: (5*2)+(4*5)+(3*2)+(2*2)+(1*3)=43 43 % 10 = 3 So 252-23-3 is a valid CAS Registry Number.
