7219-11-6 Usage
Uses
Used in Textile Industry:
Direct Green 59 is used as a dye for cotton, viscose, and their blended fabrics due to its ability to produce a vibrant green color. It is also used for printing on cotton or viscose fabrics directly, providing a convenient and efficient method for color application.
Used in Polyester/Cotton and Polyester/Stick Blended Fabrics:
Direct Green 59 is used as a dye for polyester/cotton and polyester/stick blended fabrics in a one-bath process, simplifying the dyeing process and reducing the need for multiple steps.
Standard:
Direct Green 59 meets the following standards for various properties:
Acid Resistance: 1 (ISO), 2 (AATCC)
Alkali Resistance: 4 (ISO and AATCC)
Light Fastness: 4 (ISO), 4-5 (AATCC)
Soaping: 4 (ISO), 4-5 (AATCC)
Water Fading: 4 (ISO and AATCC)
Stain Fading: 4 (ISO), 5 (AATCC)

Check Digit Verification of cas no
The CAS Registry Mumber 7219-11-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7219-11:
(6*7)+(5*2)+(4*1)+(3*9)+(2*1)+(1*1)=86
86 % 10 = 6
So 7219-11-6 is a valid CAS Registry Number.
