10,11-Dihydrobenzofluoranthene is a polycyclic aromatic hydrocarbon (PAH) with the molecular formula C20H12. It is formed by the fusion of a benzene ring onto a fluoranthene molecule, resulting in a complex, planar structure. 10,11-dihydrobenzofluoranthene is known for its potential environmental and health impacts, as PAHs are often carcinogenic and can be released into the environment through incomplete combustion of organic materials, such as in industrial processes or wildfires. Due to its chemical stability and persistence, 10,11-dihydrobenzofluoranthene can accumulate in the environment and pose risks to both ecosystems and human health.
The CAS Registry Mumber 77061-19-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively. Calculate Digit Verification of CAS Registry Number 77061-19: (7*7)+(6*7)+(5*0)+(4*6)+(3*1)+(2*1)+(1*9)=129 129 % 10 = 9 So 77061-19-9 is a valid CAS Registry Number.
