4,6-bis-(4-hydroxy-phenyl)-nonane, also known as Bisphenol S (BPS), is a synthetic organic compound that is structurally similar to Bisphenol A (BPA). It is primarily used as a substitute for BPA in the production of polycarbonate plastics and epoxy resins, which are commonly found in food containers, water bottles, and the lining of food cans. BPS has gained attention due to concerns over its potential endocrine-disrupting properties, which may mimic or interfere with the body's hormones. Research is ongoing to understand its environmental and health impacts, as it has been detected in various environmental samples and human urine, suggesting potential exposure pathways. Despite these concerns, BPS continues to be used in certain applications due to its effectiveness and the lack of comprehensive regulations banning its use.
The CAS Registry Mumber 6052-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,5 and 2 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 6052-81: (6*6)+(5*0)+(4*5)+(3*2)+(2*8)+(1*1)=79 79 % 10 = 9 So 6052-81-9 is a valid CAS Registry Number.
