6-Hydroxy-2-[3-[(1-hydroxy-4-sodiosulfo-2-naphthalenyl)azo]phenyl]-7-[(2-methylphenyl)azo]-1H-naphth[1,2-d]imidazole-8-sulfonic acid sodium salt is a complex organic compound with the molecular formula C31H22N4NaO7S2. It is a type of azo dye, characterized by the presence of azo groups (-N=N-) and a naphthalene ring. 6-Hydroxy-2-[3-[(1-hydroxy-4-sodiosulfo-2-naphthalenyl)azo]phenyl]-7-[(2-methylphenyl)azo]-1H-naphth[1,2-d]imidazole-8-sulfonic acid sodium salt is a sodium salt, indicating that it has a negatively charged sulfonic acid group (-SO3-) which is neutralized by a sodium ion (Na+). It is likely used as a colorant or dye in various applications due to its complex structure and potential to absorb and reflect light in specific wavelengths. The presence of hydroxyl, sulfonic acid, and azo groups suggests that it may have solubility properties in water and could be involved in chemical reactions related to its functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 6406-49-1 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 9 respectively.
Calculate Digit Verification of CAS Registry Number 6406-49:
(6*6)+(5*4)+(4*0)+(3*6)+(2*4)+(1*9)=91
91 % 10 = 1
So 6406-49-1 is a valid CAS Registry Number.
