886748-32-9 Usage
General Description
2,2',4,4'-Tetrabromo-5,5'-difluorodiphenyl ether, also known as BDE-47, is a chemical compound used as a flame retardant in various products such as electronic equipment, textiles, and plastics. It belongs to the class of polybrominated diphenyl ethers (PBDEs) and is known to persist in the environment and bioaccumulate in living organisms. BDE-47 has been linked to potential health hazards, including endocrine disruption, neurotoxicity, and developmental toxicity. Due to these concerns, its use has been regulated in many countries to protect human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 886748-32-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,7,4 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 886748-32:
(8*8)+(7*8)+(6*6)+(5*7)+(4*4)+(3*8)+(2*3)+(1*2)=239
239 % 10 = 9
So 886748-32-9 is a valid CAS Registry Number.
