4-Hydroxy-3-[[4'-[(1-hydroxy-4-sulfo-2-naphtyl)azo]-1,1'-biphenyl-4-yl]azo]-2,7-naphthalenedisulfonic acid trisodium salt is a complex organic compound that exhibits unique properties and characteristics. It is characterized by its purple color, which is soluble in water for a deep purple hue, slightly soluble in alcohol for a red light purple shade, and insoluble in acetone. When treated with strong sulfuric acid, it turns blue and then purple upon dilution. The dye solution changes to a purplish-red color upon the addition of strong hydrochloric acid, and turns red when mixed with a thick sodium hydroxide solution.

4Check Digit Verification of cas no
The CAS Registry Mumber 6507-83-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,0 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 6507-83:
(6*6)+(5*5)+(4*0)+(3*7)+(2*8)+(1*3)=101
101 % 10 = 1
So 6507-83-1 is a valid CAS Registry Number.
