1,12-dimethyl-5,6,6a,7,8,12b-hexahydrobenzo[c]phenanthrene-5,8-diol is a complex organic compound with a molecular formula of C21H24O2. It belongs to the class of chemicals known as polycyclic aromatic hydrocarbons, which are characterized by their multiple fused benzene rings. This specific compound features a hexahydrobenzo[c]phenanthrene core, which is a type of polycyclic aromatic structure, with two methyl groups at the 1 and 12 positions, and two hydroxyl groups at the 5 and 8 positions. The hexahydro prefix indicates that the compound has six hydrogen atoms added across the ring system, which can affect its physical properties and reactivity compared to fully unsaturated analogs. This chemical is not commonly found in everyday products but may be encountered in specific industrial applications or as a synthetic intermediate in the production of certain pharmaceuticals or other complex organic molecules.
The CAS Registry Mumber 7499-28-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 9 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7499-28: (6*7)+(5*4)+(4*9)+(3*9)+(2*2)+(1*8)=137 137 % 10 = 7 So 7499-28-7 is a valid CAS Registry Number.
