55621-21-1 Usage
General Description
PERFLUORO-3,6-DIOXAOCTANE-1,8-DIOIC ACID, also known as PFDA, is a synthetic chemical compound that belongs to the perfluoroalkyl and polyfluoroalkyl substances (PFAS) group. PFDA is widely used in the production of non-stick coatings, stain-resistant fabrics, and firefighting foams. It is known for its persistence in the environment and its ability to bioaccumulate in living organisms. Studies have linked PFDA exposure to adverse health effects, including developmental and reproductive toxicity, liver and immune system damage, and potential carcinogenic properties. As a result, PFDA has been facing increasing regulatory scrutiny and restrictions in its use.
Check Digit Verification of cas no
The CAS Registry Mumber 55621-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55621-21:
(7*5)+(6*5)+(5*6)+(4*2)+(3*1)+(2*2)+(1*1)=111
111 % 10 = 1
So 55621-21-1 is a valid CAS Registry Number.
