Vital new red is a red-colored compound that is soluble in water, slightly soluble in ethanol, and insoluble in other organic solvents. It exhibits properties such as acid resistance, alkali resistance, light fastness, and soaping. When added to strong sulfuric acid, it turns dark blue, and when mixed with strong hydrochloric acid, it becomes orange brown. Upon the addition of a thick sodium hydroxide solution, it turns red orange and forms a precipitate.

1Check Digit Verification of cas no
The CAS Registry Mumber 574-65-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,7 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.Calculate Digit Verification of CAS Registry Number 574-65:
(5*5)+(4*7)+(3*4)+(2*6)+(1*5)=82
82 % 10 = 2
So 574-65-2 is a valid CAS Registry Number.
