6406-47-9 Usage
Description
4-[(4-Amino-2-methyl-5-methoxyphenyl)azo]-1'-hydroxy-[1,2'-azobisnaphthalene]-4',6-disulfonic acid disodium salt is a dark blue to navy blue compound that is soluble in water, resulting in a navy to violet black color. It is slightly soluble in ethanol, which gives it a blue color. In strong sulfuric acid, it appears dark blue, while in diluted purple form. When the dye solution is mixed with strong hydrochloric acid, it forms a purple precipitate. When mixed with strong sodium hydroxide solution, it turns navy.

Check Digit Verification of cas no
The CAS Registry Mumber 6406-47-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6406-47:
(6*6)+(5*4)+(4*0)+(3*6)+(2*4)+(1*7)=89
89 % 10 = 9
So 6406-47-9 is a valid CAS Registry Number.
