5,10,10a,11-tetrahydro-4bH-5,10-o-benzeno-benzo[b]fluorene is a complex organic compound belonging to the class of polycyclic aromatic hydrocarbons (PAHs). It features a unique molecular structure, characterized by a benzo[b]fluorene core, which is a fusion of a benzene ring and a fluorene ring. The compound's name reflects its structure, with "5,10,10a,11-tetrahydro" indicating the presence of four hydrogen atoms in specific positions, and "4bH" denoting the hydrogen atom at the 4b position. 5,10,10a,11-tetrahydro-4bH-5,10-o-benzeno-benzo[b]fluorene is of interest in chemical research due to its potential applications in various fields, including materials science and pharmaceuticals, where its electronic properties and stability are studied. However, it is important to note that PAHs are also known for their potential environmental and health impacts, and thus, their synthesis and handling require careful consideration of safety and environmental regulations.
The CAS Registry Mumber 7281-17-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,8 and 1 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 7281-17: (6*7)+(5*2)+(4*8)+(3*1)+(2*1)+(1*7)=96 96 % 10 = 6 So 7281-17-6 is a valid CAS Registry Number.
