Benz[4,5]indeno[1,2,3-fg]naphthacene is a complex polycyclic aromatic hydrocarbon (PAH) consisting of a benzene ring fused to an indeno[1,2,3-fg]naphthacene core. This large, planar molecule features multiple fused aromatic rings, which contribute to its stability and potential applications in materials science and organic chemistry. The compound is characterized by its unique structure, which includes a central benzene ring connected to an indeno[1,2,3-fg]naphthacene system, resulting in a highly conjugated system with a large π-electron cloud. Due to its size and complexity, benz[4,5]indeno[1,2,3-fg]naphthacene is of interest to researchers studying the properties and potential applications of large PAHs, such as in the development of new materials with unique electronic and optical properties.
The CAS Registry Mumber 203-05-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 3 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 203-05: (5*2)+(4*0)+(3*3)+(2*0)+(1*5)=24 24 % 10 = 4 So 203-05-4 is a valid CAS Registry Number.
