CFCl2SO(4-C6H4Cl) is a complex chemical compound that can be described as a chlorofluorocarbon (CFC) derivative with a sulfonate group attached to an aromatic ring. CFCl2SO(4-C6H4Cl) is characterized by the presence of two chlorine atoms (Cl), one fluorine atom (F), and a sulfate group (SO4) that is connected to a chlorinated benzene ring (C6H4Cl). The chlorinated benzene ring has one chlorine atom attached to it, which is located at the 4-position relative to the sulfonate group. This type of compound may have applications in various industrial processes, such as refrigerants, solvents, or fire suppressants, due to its unique chemical properties. However, it is important to note that CFCs are known to be harmful to the ozone layer, and their production and use have been significantly reduced or banned in many countries due to environmental concerns.

The CAS Registry Mumber 1644-81-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1644-81:
(6*1)+(5*6)+(4*4)+(3*4)+(2*8)+(1*1)=81
81 % 10 = 1
So 1644-81-1 is a valid CAS Registry Number.
