It is commonly used as a solvent in various industrial applications and as a refrigerant in some cooling systems. 1,1,3,3-TETRAFLUORODIMETHYL ETHER has a low boiling point and is known for its non-flammability, making it a safe and effective alternative to more traditional solvents and refrigerants. However, it is important to handle this chemical with caution, as inhalation or ingestion can cause respiratory irritation and other health complications. Overall, 1,1,3,3-Tetrafluorodimethyl ether is a versatile chemical with a range of uses but must be used responsibly to ensure the safety of workers and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 1691-17-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1691-17:
(6*1)+(5*6)+(4*9)+(3*1)+(2*1)+(1*7)=84
84 % 10 = 4
So 1691-17-4 is a valid CAS Registry Number.

, p. 123 - 130 (2003)
The thermal decarboxylation of three dicarboxylic perfluoropolyether potassium salts of relatively short chain length has been investigated and the products and kinetics of the main reactions have been defined. From the rate constants and Arrhenius parameters data, the second decarboxylation appears to be quantitatively rather close to the first.
