β-(Ethansulfinyl)-α-phenyl-styrol, also known as ethyl phenylsulfinylstyrene, is an organic compound with the chemical formula C10H12OS. It is a colorless to pale yellow liquid with a molecular weight of 176.27 g/mol. β-(Ethansulfinyl)-α-phenyl-styrol is characterized by the presence of a styrene moiety (α-phenyl-styrol), which is a vinylbenzene structure, and an ethyl sulfinyl group (β-ethansulfinyl) attached to the styrene's β-carbon. Ethyl phenylsulfinylstyrene is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly in the production of chiral compounds due to its potential to introduce asymmetry into chemical reactions. It is also employed in the preparation of sulfoxides and sulfones, which are important in the field of organic chemistry. The compound is sensitive to oxidation and should be handled under an inert atmosphere to maintain its stability.

57642-54-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57642-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,4 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.Calculate Digit Verification of CAS Registry Number 57642-54:
(7*5)+(6*7)+(5*6)+(4*4)+(3*2)+(2*5)+(1*4)=143
143 % 10 = 3
So 57642-54-3 is a valid CAS Registry Number.
