5,6-Dichlor-perfluor-capronsaeure-anilid, also known as 5,6-dichloro-perfluorooctanesulfonic acid anilide, is a chemical compound with the molecular formula C8H4Cl2F13NO2S. It is a derivative of perfluorooctanesulfonic acid (PFOS), a perfluorinated compound known for its environmental persistence and potential health risks. 5,6-Dichlor-perfluor-capronsaeure-anilid features a perfluorinated carbon chain with a sulfonic acid group, which is then reacted with aniline to form an anilide. Due to its perfluorinated nature, it is highly resistant to degradation and can accumulate in the environment and in the food chain, posing a risk to both ecosystems and human health. As a result, the production and use of PFOS and its derivatives, including 5,6-dichloro-perfluorooctanesulfonic acid anilide, have been heavily regulated or banned in many countries due to their environmental and health concerns.
The CAS Registry Mumber 904-76-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 4 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 904-76: (5*9)+(4*0)+(3*4)+(2*7)+(1*6)=77 77 % 10 = 7 So 904-76-7 is a valid CAS Registry Number.
