3398-09-2 Usage
General Description
p-Amino-2′,3-azotoluene, also known as 2-Amino-4-methylazobenzene, is an organic compound commonly used as a dye intermediate in the manufacturing of azo dyes. This chemical is a yellow, crystalline solid that is insoluble in water but soluble in organic solvents. It is primarily used in the textile and paper industries to impart color to various products, such as clothing, fabrics, and paper materials. However,
Check Digit Verification of cas no
The CAS Registry Mumber 3398-09-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,9 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3398-09:
(6*3)+(5*3)+(4*9)+(3*8)+(2*0)+(1*9)=102
102 % 10 = 2
So 3398-09-2 is a valid CAS Registry Number.

BLACK DICHROIC DYE
-
Page/Page column 37, (2012/01/06)
Described is a black dichroic dye composition comprising 2 or more dyes, wherein at least one dye, generally a red dye and optionally a yellow dye, conforms to the formula A and at least one dye, usually a blue dye, conforms to the formula B Ar1-N=N-[Ar2-N=N-]qAr3-N=N-Ar4 (B) with symbols as defined in present claims. The dye composition is well suited for combination with liquid crystal material for use, inter alia, as polarizing film and/or in liquid crystal displays, showing, inter alia, high dichroic ratio and excellent compatibility with the LC material.
