6507-78-4 Usage
Description
Acid Red 374 is a synthetic azo dye characterized by its colorful red-yellow hue. It appears as a dark red powder that is soluble in water, producing an orange-red color, and slightly soluble in ethanol, resulting in a golden brown shade. The dye exhibits various color changes when interacting with different chemicals, such as turning red-light purple in strong sulfuric acid and orange when diluted. It is primarily used for dyeing wool, silk, and polyamide fibers.
Uses

Check Digit Verification of cas no
The CAS Registry Mumber 6507-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6507-78:
(6*6)+(5*5)+(4*0)+(3*7)+(2*7)+(1*8)=104
104 % 10 = 4
So 6507-78-4 is a valid CAS Registry Number.
