25322-17-2 Usage
General Description
Dinonylnaphthalenesulfonic acid (DNNSA) is an organic compound that belongs to the family of naphthalenesulfonic acids and sulfonates. Much of its use is industrial, particularly in the manufacturing sector, where it functions as a precursor to "superplasticizers" in concrete production, helping to reduce water content while increasing the fluidity and workability of the mixture. DNNAS typically appears as a brownish-black powdery or granulated substance. Its chemical formula is C19H18O3S. Despite its prevalent use in industrial applications, there are also concerns surrounding its environmental impact and potential health risks, such as skin and eye irritation upon contact.
Check Digit Verification of cas no
The CAS Registry Mumber 25322-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,2 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25322-17:
(7*2)+(6*5)+(5*3)+(4*2)+(3*2)+(2*1)+(1*7)=82
82 % 10 = 2
So 25322-17-2 is a valid CAS Registry Number.
