7-(Dimethylamino)-3,4-dihydroxy-1-(methoxycarbonyl)phenoxazin-5-ium chloride is a synthetic compound characterized by its dark blue-purple color. It is soluble in water, where it appears red light purple, and in ethanol, where it exhibits a blue-purple hue. When dissolved in concentrated sulfuric acid, it presents a daisy blue color, which turns magenta upon dilution. The dye's aqueous solution reacts with sodium hydroxide to form a brown precipitate, which, when dissolved in excess, results in a purple solution.

AcidCheck Digit Verification of cas no
The CAS Registry Mumber 6416-51-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.Calculate Digit Verification of CAS Registry Number 6416-51:
(6*6)+(5*4)+(4*1)+(3*6)+(2*5)+(1*1)=89
89 % 10 = 9
So 6416-51-9 is a valid CAS Registry Number.
