Silver(I) perfluorooctane sulfonate, also known as AgPFOS, is a chemical compound with the formula Ag(C8F17SO3). It is a derivative of perfluorooctane sulfonate (PFOS), a synthetic fluorosurfactant known for its exceptional resistance to degradation and its ability to repel both water and oil. PFOS has been widely used in various applications, including firefighting foams, stain repellents, and industrial processes. However, due to its persistence in the environment and potential health risks, its production and use have been phased out or restricted in many countries. Silver(I) perfluorooctane sulfonate, in particular, is a form of PFOS that has been used in antimicrobial applications, taking advantage of silver's well-known bactericidal properties. Despite its potential benefits, the use of AgPFOS is also subject to scrutiny due to the environmental and health concerns associated with PFOS compounds.
The CAS Registry Mumber 3824-94-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,2 and 4 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3824-94: (6*3)+(5*8)+(4*2)+(3*4)+(2*9)+(1*4)=100 100 % 10 = 0 So 3824-94-0 is a valid CAS Registry Number.
