Uses

Used in Construction Industry:
Sodium salt of polynaphthalene sulphonic acid is used as a superplasticizer for improving the workability and reducing the water content in concrete mixtures. This results in a more durable and resistant final product, contributing to cost savings and enhanced structural integrity.
Used in Concrete Applications:
Sodium salt of polynaphthalene sulphonic acid is used as a high-efficiency water reducer, which allows for a reduction in the amount of water needed in the concrete mix. This leads to a stronger and more resilient concrete, ultimately improving the overall quality and performance of the construction material.
Used in Dye Industry:
Sodium salt of polynaphthalene sulphonic acid is used as a dispersant, which helps in the even distribution of dye particles in the dyeing process. This ensures a more uniform and consistent color application, improving the quality of the final product.

Check Digit Verification of cas no

The CAS Registry Mumber 36290-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,2,9 and 0 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 36290-04:
(7*3)+(6*6)+(5*2)+(4*9)+(3*0)+(2*0)+(1*4)=107
107 % 10 = 7
So 36290-04-7 is a valid CAS Registry Number.
