DISPERSE YELLOW 49 is a light brown powder that exhibits bright green light yellow color. It is soluble in acetone and ethanol, and its dyeing process is affected by the presence of copper and iron ions. The dye is suitable for a pH value of three to five and is not recommended for high temperature and high pressure dyeing. It is prone to decomposition in high temperature alkaline conditions. The optimal temperature for hot melt dyeing is 195-200°C, while the carrier dyeing method is applicable at 100°C with pH control around five.

5Check Digit Verification of cas no
The CAS Registry Mumber 54824-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,2 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.Calculate Digit Verification of CAS Registry Number 54824-37:
(7*5)+(6*4)+(5*8)+(4*2)+(3*4)+(2*3)+(1*7)=132
132 % 10 = 2
So 54824-37-2 is a valid CAS Registry Number.
