Description
Vat Orange 15 is a yellow-orange to orange-red powder that is slightly soluble in Nitrobenzene, 1,2,3,4-Tetrahydronaphthalene, and Xylene, but insoluble in Ethanol. It exhibits unique color-changing properties when exposed to acidic or alkaline environments, with strong sulfuric acid turning it green light blue and orange when diluted, while alkaline reduction results in a brown body hidden color, and acid reduction yields a dark yellow body hidden color.

Check Digit Verification of cas no
The CAS Registry Mumber 2379-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,7 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2379-78:
(6*2)+(5*3)+(4*7)+(3*9)+(2*7)+(1*8)=104
104 % 10 = 4
So 2379-78-4 is a valid CAS Registry Number.
