16757-81-6 Usage
General Description
3-Methylbenzo[a]pyrene, also known as 3-Methylchrysene, is a polycyclic aromatic hydrocarbon (PAH) that is formed during the incomplete combustion of organic matter. It is classified as a potential human carcinogen and has been shown to be mutagenic and genotoxic. 3-Methylbenzo[a]pyrene is often found in environmental pollutants such as vehicle exhaust, industrial emissions, and cigarette smoke. Exposure to this chemical has been linked to an increased risk of developing cancer, particularly in the lung, skin, and bladder. Additionally, 3-Methylbenzo[a]pyrene is known to bind to DNA and form adducts, potentially leading to cellular damage and mutation. Efforts to mitigate exposure to this hazardous chemical are essential in reducing the incidence of related health problems.
Check Digit Verification of cas no
The CAS Registry Mumber 16757-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16757-81:
(7*1)+(6*6)+(5*7)+(4*5)+(3*7)+(2*8)+(1*1)=136
136 % 10 = 6
So 16757-81-6 is a valid CAS Registry Number.
