N-perfluorooctanesulfinic acid (PFOS) is a synthetic chemical compound characterized by a perfluorinated carbon chain and a sulfinic acid group. It is known for its exceptional resistance to heat, water, and oil, which has made it a valuable component in various industrial applications, such as in the production of non-stick coatings, fire-fighting foams, and stain-resistant textiles. However, due to its persistence in the environment and potential health risks, including bioaccumulation in living organisms and toxicity, PFOS has been the subject of significant regulatory attention and is being phased out or replaced in many countries.

647-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 647-29-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 7 respectively; the second part has 2 digits, 2 and 9 respectively.Calculate Digit Verification of CAS Registry Number 647-29:
(5*6)+(4*4)+(3*7)+(2*2)+(1*9)=80
80 % 10 = 0
So 647-29-0 is a valid CAS Registry Number.
