2,2,3,3,3-Pentachlor-1,1-bis-<4-brom-phenyl>-propan, also known as Pentabromodiphenyl propane (PBDPP), is a brominated flame retardant chemical compound. It consists of a propane chain with two 4-bromophenyl groups attached to the terminal carbon atoms and five chlorine atoms distributed across the molecule. PBDPP is primarily used in the production of flame-resistant materials, such as plastics, textiles, and electronics, due to its ability to inhibit combustion. However, concerns have been raised about its potential environmental and health impacts, as it can accumulate in ecosystems and pose risks to both wildlife and humans. As a result, the use of PBDPP and similar brominated flame retardants has been restricted or banned in some countries.
The CAS Registry Mumber 848-39-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 8 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 848-39: (5*8)+(4*4)+(3*8)+(2*3)+(1*9)=95 95 % 10 = 5 So 848-39-5 is a valid CAS Registry Number.
