Uses
Used in Textile Industry:
Disperse Red 5 is used as a dye for textiles, particularly for the production of navy and black colors. It is suitable for high-temperature, high-pressure dyeing and carrier dyeing, with a hot melt temperature of 190 to 200°C. The dye provides good ironing, light, perspiration, and washing fastness, with ISO ratings ranging from 3-5.
Used in Direct Printing:
Disperse Red 5 is used in direct printing on fabrics, allowing for the creation of various designs and patterns. It is also suitable for discharge printing, which involves removing the dye from specific areas of the fabric to create a design.

Check Digit Verification of cas no
The CAS Registry Mumber 3769-57-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,6 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3769-57:
(6*3)+(5*7)+(4*6)+(3*9)+(2*5)+(1*7)=121
121 % 10 = 1
So 3769-57-1 is a valid CAS Registry Number.
