26571-11-9 Usage
General Description
26-(nonylphenoxy)-3,6,9,12,15,18,21,24-octaoxahexacosan-1-ol, also known as NP-26, is a nonionic surfactant commonly used in the production of various household and industrial products. It is a long-chain alcohol ethoxylate, consisting of a nonylphenol group attached to a chain of 26 ethylene oxide units. NP-26 is valued for its ability to effectively lower the surface tension of liquids, making it useful in applications such as detergents, emulsifiers, and wetting agents. However, concerns have been raised about its potential environmental and human health impacts, as nonylphenol compounds are known to be endocrine disruptors and harmful to aquatic ecosystems. As a result, efforts are being made to find alternative, less harmful chemicals to replace NP-26 in various applications.
Check Digit Verification of cas no
The CAS Registry Mumber 26571-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,5,7 and 1 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 26571-11:
(7*2)+(6*6)+(5*5)+(4*7)+(3*1)+(2*1)+(1*1)=109
109 % 10 = 9
So 26571-11-9 is a valid CAS Registry Number.
