35545-57-4 Usage
General Description
Poly(oxy-1,2-ethanediyl), .alpha.-2-naphthalenyl-.omega.-hydroxy-, also known as Nonylphenol ethoxylate (NPE), is a nonionic surfactant that is commonly used in a variety of industrial and consumer products. It is a complex mixture of compounds that result from the ethoxylation of nonylphenol, which is produced from the reaction of nonene and phenol. NPEs are widely used as emulsifiers, wetting agents, and detergents in industrial applications such as textile processing, agrochemicals, and cleaning products. However, NPEs have been identified as persistent organic pollutants and are known to have toxic effects on aquatic organisms, leading to restrictions in their use and a push towards finding more sustainable alternatives.
Check Digit Verification of cas no
The CAS Registry Mumber 35545-57-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,5,4 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35545-57:
(7*3)+(6*5)+(5*5)+(4*4)+(3*5)+(2*5)+(1*7)=124
124 % 10 = 4
So 35545-57-4 is a valid CAS Registry Number.
