Tetrafluorthiiran, also known as tetrafluorothiirane or 1,1,3,3-tetrafluorothietane, is a halogenated cyclic ether with the chemical formula C2H2F4S. It is a colorless, volatile liquid with a pungent odor. Tetrafluorthiiran is synthesized by the reaction of ethylene with hydrogen fluoride and sulfur dioxide. Tetrafluorthiiran is primarily used as an intermediate in the production of various fluorochemicals, such as refrigerants, fire extinguishers, and solvents. Due to its high reactivity and potential toxicity, it requires careful handling and storage.
The CAS Registry Mumber 767-38-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 7 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 767-38: (5*7)+(4*6)+(3*7)+(2*3)+(1*8)=94 94 % 10 = 4 So 767-38-4 is a valid CAS Registry Number.
