5-Methoxy-benzo[c]phenanthren is a polycyclic aromatic hydrocarbon (PAH) with the chemical formula C21H14O. It is a derivative of benzo[c]phenanthrene, featuring a methoxy group (-OCH3) attached to the 5th carbon atom. 5-Methoxy-benzophenanthren is known for its potential environmental and health impacts, as PAHs are often found in polluted air, water, and soil, and some are classified as carcinogenic. The presence of the methoxy group can influence its chemical properties, such as solubility and reactivity, compared to other PAHs. Due to its complex structure and potential health risks, 5-methoxy-benzo[c]phenanthren is a subject of interest in environmental chemistry and toxicology research.
The CAS Registry Mumber 4235-03-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 5 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4235-03: (6*4)+(5*2)+(4*3)+(3*5)+(2*0)+(1*3)=64 64 % 10 = 4 So 4235-03-4 is a valid CAS Registry Number.
