DIRECT FAST VIOLET 2RL is a purple dye that is soluble in water, producing a red to red-light purple color. It is also adequately soluble in alcohol. The dye exhibits unique reactions with acids and bases, turning blue in strong sulfuric acid and purple when diluted. When mixed with strong hydrochloric acid, the dye solution turns blue-purple and forms a precipitate, while the addition of sodium hydroxide solution results in a strong purplish-red precipitate.

Check Digit Verification of cas no

The CAS Registry Mumber 6227-10-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,2 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6227-10:
(6*6)+(5*2)+(4*2)+(3*7)+(2*1)+(1*0)=77
77 % 10 = 7
So 6227-10-7 is a valid CAS Registry Number.
