7-phenylbenzo[k]tetraphene is a polycyclic aromatic hydrocarbon (PAH) consisting of a benzo[k]tetraphene core with a phenyl group attached at the 7th position. It is a planar, conjugated molecule with a complex structure, featuring four fused benzene rings and a central tetraphene ring. 7-phenylbenzo[k]tetraphene is known for its potential applications in organic electronics, such as in the development of organic semiconductors and light-emitting materials, due to its unique electronic properties. However, like other PAHs, 7-phenylbenzo[k]tetraphene may also exhibit toxicological properties, and further research is needed to understand its environmental and health impacts fully.

3781-43-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3781-43-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,8 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3781-43:
(6*3)+(5*7)+(4*8)+(3*1)+(2*4)+(1*3)=99
99 % 10 = 9
So 3781-43-9 is a valid CAS Registry Number.
