55840-82-9 Usage
General Description
BASIC BLUE 4 is a synthetic organic compound belonging to the class of triarylmethane dyes. It is commonly used as a dye in the textile and paper industries, as well as in the production of inks and paints. BASIC BLUE 4 is known for its vibrant blue color and high lightfastness, making it a popular choice for coloring various materials. However, it has been associated with potential health and environmental risks, as some studies have found it to be toxic to aquatic organisms and to have the potential to cause allergic reactions in humans. As a result, its use is regulated in some regions and industries.
Check Digit Verification of cas no
The CAS Registry Mumber 55840-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,4 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55840-82:
(7*5)+(6*5)+(5*8)+(4*4)+(3*0)+(2*8)+(1*2)=139
139 % 10 = 9
So 55840-82-9 is a valid CAS Registry Number.
