6222-63-5 Usage
Description
Acid Red 137 is a synthetic dye characterized by its yellow light red color. It is soluble in water, displaying a red hue, and in alcohol, where it exhibits a red-orange shade. When it comes into contact with strong sulfuric acid, the product turns red, which then turns yellow-orange upon dilution. In a water solution, the addition of strong hydrochloric acid results in a red-brown precipitate, while the introduction of a thick sodium hydroxide solution yields a yellow-brown color.

Check Digit Verification of cas no
The CAS Registry Mumber 6222-63-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 6222-63:
(6*6)+(5*2)+(4*2)+(3*2)+(2*6)+(1*3)=75
75 % 10 = 5
So 6222-63-5 is a valid CAS Registry Number.
