Disodium 3-aminonaphthalene-2,7-disulphonate is a chemical compound with the formula C10H7NNa2O6S2. It belongs to the class of aminonaphthalene disulphonates and is commonly used as a fluorescent dye. Disodium 3-aminonaphthalene-2,7-disulphonate has two sulfonic acid groups (-SO3H) attached to the naphthalene ring, while a sodium ion is present to balance the charge. Its structure allows it to exhibit bright green fluorescence, making it useful in a variety of applications such as biological staining, protein labeling, and flow cytometry analysis. Due to its ability to bind to specific cellular components and exhibit bright emission, it is widely employed in research and medical fields for visualizing cellular structures and biological processes.
Check Digit Verification of cas no
The CAS Registry Mumber 135-50-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 135-50:
(5*1)+(4*3)+(3*5)+(2*5)+(1*0)=42
42 % 10 = 2
So 135-50-2 is a valid CAS Registry Number.
