Reactive Red 11 is a purplish red powder that exhibits colorful red to blue light shades. It has unique properties when reacting with acids and bases, turning purple in strong sulfuric acid and blue light red in diluted form, while remaining red in nitric acid even when diluted. Its aqueous solution is red, which turns light yellow upon the addition of sodium hydroxide and further turns into a light yellow precipitate with the addition of boric acid.

4Check Digit Verification of cas no
The CAS Registry Mumber 12226-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.Calculate Digit Verification of CAS Registry Number 12226-08:
(7*1)+(6*2)+(5*2)+(4*2)+(3*6)+(2*0)+(1*8)=63
63 % 10 = 3
So 12226-08-3 is a valid CAS Registry Number.
