3486-30-4 Usage
Description
ALPHAZURINE A, also known as Patent Blue A (CAS# 3486-30-4), is an organic acid dye characterized by its colorful green light blue appearance in the form of a blue powder. It is soluble in water, with its ethanol solution exhibiting a blue color. When exposed to strong sulfuric acid, it turns olive green, and upon dilution, it forms a yellow precipitate. At room temperature, ALPHAZURINE A forms a transparent green light blue aqueous solution without any gathering tendency. The addition of sodium hydroxide leads to a color change upon cooling, and when heated to boiling, the color shifts from blue to violet, resulting in a precipitate. It reacts with copper and iron ions, turning dark green in color. ALPHAZURINE A is not sensitive to heavy chromate salts and is known for its use in various industries due to its dyeing and coloring properties.

Check Digit Verification of cas no
The CAS Registry Mumber 3486-30-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,8 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3486-30:
(6*3)+(5*4)+(4*8)+(3*6)+(2*3)+(1*0)=94
94 % 10 = 4
So 3486-30-4 is a valid CAS Registry Number.
