Naphthalenesulfonic acid, methyl-, sodium salt, polymer with formaldehyde, also known as sodium naphthalene formaldehyde (SNF), is a versatile chemical that is widely used in industries such as construction, agriculture, and textiles. It is a water-soluble polymer that is often used as a dispersant and fluidizer in concrete and cement formulations to improve workability and reduce water content. Additionally, it is used as a dispersing agent in agricultural pesticides and as a wetting agent in textile and dye manufacturing. SNF is also used in the petroleum industry as a drilling mud additive to enhance fluid properties. Its unique polymer structure and formaldehyde cross-linking make it an effective and versatile chemical in various industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 9008-64-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 8 respectively; the second part has 2 digits, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 9008-64: (6*9)+(5*0)+(4*0)+(3*8)+(2*6)+(1*4)=94 94 % 10 = 4 So 9008-64-4 is a valid CAS Registry Number.
