4-[[4-(Dimethylamino)phenyl]azo]-2,6-dimethylpyridine 1-oxide, also known as Solvent Yellow 33, is an organic compound characterized by its vibrant yellow color. It is a member of the azo class of dyes, which are known for their ability to form strong, stable colors. This particular compound is synthesized by coupling a dimethylamino-substituted aniline with a 2,6-dimethylpyridine derivative, and the presence of the pyridine 1-oxide group enhances its solubility and stability. Solvent Yellow 33 is primarily used as a dye in various solvents and as a pigment in the coloration of plastics, inks, and paints. Its chemical structure, with a dimethylamino group providing a basic character and the azo linkage contributing to its color, makes it a versatile and widely used industrial chemical.

7349-99-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7349-99-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7349-99:
(6*7)+(5*3)+(4*4)+(3*9)+(2*9)+(1*9)=127
127 % 10 = 7
So 7349-99-7 is a valid CAS Registry Number.
