α,α'-Bis-(ethylthio)-α,α,α',α'-tetrafluor-p-xylol, also known as 2,2'-(1,1,2,2-tetrafluoro-1,3-propanediyl)bis(ethylsulfanylethane), is an organic compound with the chemical formula C10H16F4S2. It is a colorless liquid with a molecular weight of 310.35 g/mol. α,α'-Bis-(ethylthio)-α,α,α',α'-tetrafluor-p-xylol is characterized by its symmetrical structure, featuring two ethylthio groups (-C2H5S) attached to a central tetrafluorop-xylylene (-CF2-CF2-CF2-CF2-) core. It is used as a ligand in the synthesis of metal complexes, particularly in the preparation of palladium catalysts for cross-coupling reactions in organic chemistry. Due to its unique electronic properties and steric bulk, it can influence the reactivity and selectivity of the resulting catalysts.

Check Digit Verification of cas no

The CAS Registry Mumber 3200-26-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,0 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3200-26:
(6*3)+(5*2)+(4*0)+(3*0)+(2*2)+(1*6)=38
38 % 10 = 8
So 3200-26-8 is a valid CAS Registry Number.
