7-(2-chlorophenyl)tetraphene is a chemical compound with the molecular formula C20H13Cl. It is a derivative of tetraphene, a polycyclic aromatic hydrocarbon consisting of four fused benzene rings. The presence of a 2-chlorophenyl group attached to the 7th position of the tetraphene core introduces a chlorine atom to the molecule, which can significantly alter its chemical properties and reactivity. 7-(2-chlorophenyl)tetraphene may have potential applications in various fields, such as materials science, pharmaceuticals, or as intermediates in organic synthesis. However, it is essential to consider the potential environmental and health impacts associated with the use of chlorinated compounds, as they can be persistent and toxic.

Check Digit Verification of cas no

The CAS Registry Mumber 1557-89-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1557-89:
(6*1)+(5*5)+(4*5)+(3*7)+(2*8)+(1*9)=97
97 % 10 = 7
So 1557-89-7 is a valid CAS Registry Number.
