Sodium 5-[(4,5-dihydro-3-methyl-5-oxo-1-phenyl-1H-pyrazol-4-yl)azo]-4-hydroxytoluene-3-sulphonate is a dark yellow-red powder that is soluble in water, resulting in a yellow-brown solution. It exhibits different colors when dissolved in concentrated sulfuric acid (orange-red) and concentrated hydrochloric acid (yellow-brown). Upon the addition of sodium hydroxide to its dye aqueous solution, the color turns yellow.

3Check Digit Verification of cas no
The CAS Registry Mumber 6232-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,3 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 6232-55:
(6*6)+(5*2)+(4*3)+(3*2)+(2*5)+(1*5)=79
79 % 10 = 9
So 6232-55-9 is a valid CAS Registry Number.
