Anthra[2,1-a]aceanthrylene is a polycyclic aromatic hydrocarbon (PAH) with a unique structure consisting of three fused benzene rings and two additional five-membered rings. anthra<2,1-a>aceanthrylene is characterized by its molecular formula C20H12 and has a planar, non-alternant structure. It is known for its stability and resistance to chemical reactions, which makes it less reactive compared to other PAHs. Anthra[2,1-a]aceanthrylene is of interest in chemical research due to its potential applications in materials science and as a building block for more complex organic molecules. However, like other PAHs, it may also have environmental and health implications due to its potential carcinogenic properties, and thus its presence in the environment is a subject of concern.

Check Digit Verification of cas no

The CAS Registry Mumber 203-21-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,0 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 203-21:
(5*2)+(4*0)+(3*3)+(2*2)+(1*1)=24
24 % 10 = 4
So 203-21-4 is a valid CAS Registry Number.
