128416-19-3 Usage
General Description
C.I. Reactive Blue 220, also known to chemists as a 'reactive dye,' is a classification of synthetic dye deeply admired within the textile industry for its long-lasting attributes. This specific chemical compound contains reactive groups that foster bonds with the material, increasing its longevity and making it highly resistant to washing or exposure to sunlight. It is generally used in the dyeing of cotton, silk, wool, and nylon. Despite being highly effective as a coloring agent, it does pose significant environmental concerns due to the toxicity and non-biodegradability of leftover residues, posing potential harm to aquatic life and the broader ecosystem.
Check Digit Verification of cas no
The CAS Registry Mumber 128416-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,1 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128416-19:
(8*1)+(7*2)+(6*8)+(5*4)+(4*1)+(3*6)+(2*1)+(1*9)=123
123 % 10 = 3
So 128416-19-3 is a valid CAS Registry Number.
