1649-56-5 Usage
General Description
Ethyl 11H-perfluoroundecanoate is a chemical compound often used in the industrial and manufacturing sectors due to its unique characteristics. With the chemical formula C13H5F21O2, this chemical belongs to the family of perfluorocarboxylic acids and their derivatives. It is highly stable and non-reactive due to the strength of the carbon-fluorine bonds and is highly resistant to heat and chemical agents. It is also known for its ability to reduce the surface tension of water, which makes it an effective surfactant and widely used in applications such as surface coatings, fire fighting foams, and electronics. However, due to its persistent and bio-accumulative nature, concerns have been raised about its environmental and health impacts, particularly because traces have been found in various ecosystems and in human tissues.
Check Digit Verification of cas no
The CAS Registry Mumber 1649-56-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1649-56:
(6*1)+(5*6)+(4*4)+(3*9)+(2*5)+(1*6)=95
95 % 10 = 5
So 1649-56-5 is a valid CAS Registry Number.
