5281-04-9 Usage
Uses
Used in Printing Ink Industry:
Pigment Red 57:1 is used as a printing ink pigment for various applications in the printing industry. It is particularly favored for its brilliant shade that aligns with the standard "magenta" shade of the European scale for multicolor, letterpress, and offset printing. The pigment's high tinting strength, good lightfastness, and solvent resistance make it suitable for use in letterpress and offset printing, as well as illustration and packaging gravure printing.
Used in Letterpress Printing:
In letterpress printing, Pigment Red 57:1 is utilized as a pigment for its ability to produce a vibrant magenta shade with high tinting strength. Its lightfastness and solvent resistance contribute to the durability and quality of the printed materials.
Used in Offset Printing:
For offset printing, Pigment Red 57:1 serves as a crucial pigment due to its consistent magenta shade, which is essential for accurate color reproduction. Its heat resistance and resistance to acids and alkalis make it an ideal choice for this printing process.
Used in Gravure Printing:
In illustration and packaging gravure printing, Pigment Red 57:1 is employed for its ability to create a bluish shade with high tinting strength. Its lightfastness ensures that the printed materials maintain their color vibrancy over time, while its solvent resistance aids in the printing process.

Check Digit Verification of cas no
The CAS Registry Mumber 5281-04-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5281-04:
(6*5)+(5*2)+(4*8)+(3*1)+(2*0)+(1*4)=79
79 % 10 = 9
So 5281-04-9 is a valid CAS Registry Number.
