2429-81-4 Usage
Description
Tetrasodium 5-[[4'-[[2,6-diamino-3-[[8-hydroxy-3,6-disulphonato-7-[(4-sulphonato-1-naphthyl)azo]-2-naphthyl]azo]-5-tolyl]azo][1,1'-biphenyl]-4-yl]azo]salicylate is a complex organic compound with a unique chemical structure. It is characterized by its red light brown color and solubility properties, being soluble in water for a yellow brown color, adequately soluble in ethanol and soluble fiber element, and insoluble in other organic solvents. The compound also exhibits various color changes when exposed to different acids and bases, such as blue-ray purple or brown and violet black in strong sulfuric acid, brown in nitric acid, and blue-ray red in a 10% sodium hydroxide solution. Additionally, it has the ability to form orange brown precipitation when mixed with a thick sodium hydroxide solution.

Check Digit Verification of cas no
The CAS Registry Mumber 2429-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,2 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2429-81:
(6*2)+(5*4)+(4*2)+(3*9)+(2*8)+(1*1)=84
84 % 10 = 4
So 2429-81-4 is a valid CAS Registry Number.
