Phenylene Blue, also known as Phenylenediamine Blue or Acid Blue 80, is a synthetic organic compound with the chemical formula C32H24N6Na4O14S4. It is a dark blue, water-soluble dye that belongs to the class of azo dyes. Phenylene Blue is widely used in various applications, including the dyeing of textiles, paper, and leather, as well as in the production of ink and pigments. The compound is known for its high color strength, good lightfastness, and resistance to washing and bleaching. However, it is important to note that Phenylene Blue, like other azo dyes, may pose health and environmental concerns due to its potential to release harmful aromatic amines during degradation. As a result, its use is regulated in certain industries, and alternative, safer dyes are being developed to replace it.

Check Digit Verification of cas no

The CAS Registry Mumber 6359-34-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6359-34:
(6*6)+(5*3)+(4*5)+(3*9)+(2*3)+(1*4)=108
108 % 10 = 8
So 6359-34-8 is a valid CAS Registry Number.
