Dibenzo[b,mno]fluoranthene is a polycyclic aromatic hydrocarbon (PAH) consisting of five fused aromatic rings. It is a structural isomer of dibenzo[a,l]pyrene and is characterized by its molecular formula C24H14. Dibenzo[b,mno]fluoranthene 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 incomplete combustion of organic materials. Dibenzo[b,mno]fluoranthene is classified as a probable human carcinogen by the International Agency for Research on Cancer (IARC), indicating that it may cause cancer in humans. Due to its persistence in the environment and potential to bioaccumulate in living organisms, it poses a risk to both human health and the ecosystem.
The CAS Registry Mumber 668-30-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 8 respectively; the second part has 2 digits, 3 and 0 respectively. Calculate Digit Verification of CAS Registry Number 668-30: (5*6)+(4*6)+(3*8)+(2*3)+(1*0)=84 84 % 10 = 4 So 668-30-4 is a valid CAS Registry Number.
