3H-benzo[c,d]pyren-3-one is a polycyclic aromatic hydrocarbon (PAH) derivative, characterized by its unique chemical structure consisting of a benzene ring fused to a pyrene core. 3H-benzopyren-3-one is known for its potential carcinogenic and mutagenic properties, as it can interact with DNA and cause genetic mutations. It is formed during the incomplete combustion of organic materials, such as in industrial processes, vehicle emissions, and cigarette smoke. Due to its hazardous nature, there is a growing interest in studying its environmental impact, as well as developing methods for its detection and removal from contaminated sites.
The CAS Registry Mumber 4558-17-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 8 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4558-17: (6*4)+(5*5)+(4*5)+(3*8)+(2*1)+(1*7)=102 102 % 10 = 2 So 4558-17-2 is a valid CAS Registry Number.
