8-Phenylfluoranthen is a polycyclic aromatic hydrocarbon (PAH) consisting of a fluoranthene molecule with a phenyl group attached at the 8th position. It is a colorless, crystalline solid with a molecular formula of C22H14 and a molecular weight of 278.34 g/mol. 8-Phenylfluoranthen is formed through the incomplete combustion of organic materials, such as coal, oil, and gas, and is also found in various environmental sources, including air, water, and soil. Due to its potential carcinogenic and mutagenic properties, 8-Phenylfluoranthen is a subject of concern in terms of environmental and human health risks.
The CAS Registry Mumber 4889-56-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,8 and 9 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 4889-56: (6*4)+(5*8)+(4*8)+(3*9)+(2*5)+(1*6)=139 139 % 10 = 9 So 4889-56-9 is a valid CAS Registry Number.
