3,4-bis-(4-hydroxy-2-methyl-phenyl)-hexane, 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 building block in the production of various polymers, including epoxy resins and polycarbonate plastics. BPS has gained attention as a potential substitute for BPA in consumer products due to concerns over BPA's potential health effects. However, recent studies have raised concerns about BPS as well, suggesting it may have similar endocrine-disrupting properties to BPA, which could potentially impact human health and the environment. As a result, there is ongoing research and debate about the safety and regulation of BPS in consumer products.

4437-94-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4437-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4437-94:
(6*4)+(5*4)+(4*3)+(3*7)+(2*9)+(1*4)=99
99 % 10 = 9
So 4437-94-9 is a valid CAS Registry Number.
