Benzo[b]biphenylene, also known as benzo[b]chrysene, is a polycyclic aromatic hydrocarbon (PAH) consisting of two fused benzene rings with a biphenyl structure. It is a colorless, crystalline solid with a molecular formula of C20H12 and a molecular weight of 252.31 g/mol. benzo[b]biphenylene is formed during the incomplete combustion of organic materials, such as coal, oil, and tobacco, and is considered a potential environmental pollutant due to its persistence and toxicity. Benzo[b]biphenylene has been classified as a Group 2B carcinogen by the International Agency for Research on Cancer (IARC), indicating that it is possibly carcinogenic to humans. It is also known to cause various health issues, including respiratory and skin problems, and has been detected in air, water, and soil samples. Due to its potential health risks, efforts are being made to monitor and control the release of benzo[b]biphenylene into the environment.

259-56-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 259-56-3 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 9 respectively; the second part has 2 digits, 5 and 6 respectively.Calculate Digit Verification of CAS Registry Number 259-56:
(5*2)+(4*5)+(3*9)+(2*5)+(1*6)=73
73 % 10 = 3
So 259-56-3 is a valid CAS Registry Number.
