1,1,2,5,5-pentachloro-penta-1,4-dien-3-ol, also known as PCPD, is a chlorinated organic compound with the molecular formula C5H3Cl5O. It is a colorless to pale yellow liquid with a pungent odor. PCPD is a highly toxic and persistent environmental pollutant, classified as a polychlorinated diene. It is formed as a byproduct during the production of certain chlorinated chemicals, such as hexachlorocyclohexane (HCH), and can also be released into the environment through industrial processes and waste disposal. Due to its lipophilic nature, PCPD can accumulate in the food chain, posing a risk to both human health and the environment. It has been associated with various adverse effects, including endocrine disruption, reproductive toxicity, and potential carcinogenicity. As a result, its production and use have been restricted or banned in many countries under international agreements like the Stockholm Convention on Persistent Organic Pollutants.
The CAS Registry Mumber 6115-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,1 and 5 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6115-57: (6*6)+(5*1)+(4*1)+(3*5)+(2*5)+(1*7)=77 77 % 10 = 7 So 6115-57-7 is a valid CAS Registry Number.
