OXAMINE BLUE B is a blue-colored dye that exhibits various color changes when exposed to different chemical environments. It is soluble in water, showing a range of colors from purple to red light blue. When exposed to strong sulfuric acid, it turns green light blue, and when diluted, it becomes red light purple. In nitric acid, it turns yellow. The dye solution changes to blue purple when strong hydrochloric acid is added, and it turns purplish red to red light purple when thick sodium hydroxide solution is added.

3Check Digit Verification of cas no
The CAS Registry Mumber 6428-97-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.Calculate Digit Verification of CAS Registry Number 6428-97:
(6*6)+(5*4)+(4*2)+(3*8)+(2*9)+(1*7)=113
113 % 10 = 3
So 6428-97-3 is a valid CAS Registry Number.
