α,α,α',α'-Tetrafluorodiethyl ether, also known as hexafluoro-2,5-bis(trifluoromethyl)-1,4-dioxane, is a colorless, volatile, and highly stable liquid with the chemical formula C4F8O2. It is a perfluorinated ether, which means that all hydrogen atoms in the molecule have been replaced by fluorine atoms. α,α,α',α'-Tetrafluordiaethylaether is known for its low boiling point (29.5°C), high chemical stability, and low reactivity, making it useful in various applications such as a solvent in organic synthesis, a cleaning agent, and a component in fire-extinguishing foams. Due to its nonflammable nature and low toxicity, it is also considered a safer alternative to some traditional solvents.
The CAS Registry Mumber 38217-11-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,2,1 and 7 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 38217-11: (7*3)+(6*8)+(5*2)+(4*1)+(3*7)+(2*1)+(1*1)=107 107 % 10 = 7 So 38217-11-7 is a valid CAS Registry Number.
