Description
Mordant Orange 3 is a dark red to light orange dye that is soluble in water, producing a yellow-orange solution. When exposed to concentrated sulfuric acid, it turns yellow and forms an orange solution upon dilution, with a yellow precipitate. In concentrated sodium hydroxide solution, it exhibits an orange color. It is primarily used for color matching in dyeing processes for various materials, offering higher dyeing fastness.

Check Digit Verification of cas no
The CAS Registry Mumber 6359-86-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,5 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6359-86:
(6*6)+(5*3)+(4*5)+(3*9)+(2*8)+(1*6)=120
120 % 10 = 0
So 6359-86-0 is a valid CAS Registry Number.
