1-(3-Fluorophenyl)-2-(2-fluorophenyl)-1-hydroxy-ethan, also known as 1-(3-fluorophenyl)-2-(2-fluorophenyl)-1-ethanol, is an organic compound characterized by the presence of two fluorophenyl groups and a hydroxyl group attached to an ethyl chain. The molecule consists of a central carbon atom bonded to a hydroxyl group (-OH), an ethyl group (-CH2CH3), and two phenyl rings, one of which is substituted with a fluorine atom at the 3rd position and the other at the 2nd position. This chemical structure endows the compound with unique properties, such as increased lipophilicity due to the fluorine atoms, which can affect its reactivity, solubility, and potential applications in various fields, including pharmaceuticals and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 4557-81-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4557-81:
(6*4)+(5*5)+(4*5)+(3*7)+(2*8)+(1*1)=107
107 % 10 = 7
So 4557-81-7 is a valid CAS Registry Number.
