149697-40-5 Usage
General Description
BIS(4-CHLOROOCTAFLUOROBUTYL)ETHER is a chemical compound that belongs to the family of perfluorinated compounds. It is used as a surfactant, solvent, and anti-foaming agent in various industrial applications, including in the production of polymers, electronics, and firefighting foams. This chemical is known for its high thermal stability, chemical inertness, and low surface tension, making it suitable for use in extreme environments. However, BIS(4-CHLOROOCTAFLUOROBUTYL)ETHER has raised environmental and health concerns due to its persistence and potential bioaccumulative properties, which have led to regulatory restrictions and phase-out efforts in some countries.
Check Digit Verification of cas no
The CAS Registry Mumber 149697-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,6,9 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 149697-40:
(8*1)+(7*4)+(6*9)+(5*6)+(4*9)+(3*7)+(2*4)+(1*0)=185
185 % 10 = 5
So 149697-40-5 is a valid CAS Registry Number.

Normally liquid, omega-hydrofluoroalkyl ether compounds (and selected mixtures thereof) have a saturated perfluoroaliphatic chain of carbon atoms interrupted by one or more ether oxygen atoms. The compounds can be prepare, e.g. by decarboxylation of the corresponding fluoroalkyl ether carboxylic acids and are useful, e.g., in cleaning and drying applications.
