Description
ACID RED 9 is a synthetic dye characterized by its yellow light red color. It is slightly soluble in cold water and becomes soluble in hot water, exhibiting a yellow-red hue. When treated with strong sulfuric acid, it turns red, and upon dilution, a brown precipitate forms. In an aqueous solution, the addition of hydrochloric acid results in brown precipitation, while the addition of sodium hydroxide leads to red-brown precipitation.

Check Digit Verification of cas no
The CAS Registry Mumber 8003-59-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 8003-59:
(6*8)+(5*0)+(4*0)+(3*3)+(2*5)+(1*9)=76
76 % 10 = 6
So 8003-59-6 is a valid CAS Registry Number.
