Dibenzo[a,l]tetracene is a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, with the molecular formula C20H12. It is a colorless to pale yellow crystalline solid that is insoluble in water but soluble in organic solvents. DIBENZO[A,L]TETRACENE is known for its potential environmental and health impacts, as it can be found in polluted air, water, and soil, often as a result of incomplete combustion of organic materials. Dibenzo[a,l]tetracene is classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC), and exposure to it may lead to various health issues, including skin and lung problems. Due to its persistence and toxicity, it is important to monitor and control the release of dibenzo[a,l]tetracene into the environment.
The CAS Registry Mumber 226-86-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,2 and 6 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 226-86: (5*2)+(4*2)+(3*6)+(2*8)+(1*6)=58 58 % 10 = 8 So 226-86-8 is a valid CAS Registry Number.
