2923-68-4 Usage
General Description
3,5,7,8-Tetrachloroperfluorooctanoic acid, also known as TCFPOA, is a man-made chemical compound that belongs to the class of per- and polyfluoroalkyl substances (PFAS). It is a persistent organic pollutant and has been found to be present in the environment, in wildlife, and in humans. TCFPOA is primarily used as a surfactant in the production of polymers and in the manufacturing of stain-resistant coatings, firefighting foams, and other industrial processes. It is highly resistant to degradation and has been associated with adverse health effects, including potential carcinogenic, developmental, and reproductive issues. Due to its widespread presence and potential health hazards, efforts are being made to phase out the use of TCFPOA and to mitigate its environmental and human health impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 2923-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2923-68:
(6*2)+(5*9)+(4*2)+(3*3)+(2*6)+(1*8)=94
94 % 10 = 4
So 2923-68-4 is a valid CAS Registry Number.
