66675-89-6 Usage
Uses
Used in Textile Industry:
ALIZARIN BLUE S is used as a dye for coloring textiles due to its unique color properties and solubility in water and ethanol. It provides good ironing fastness, light fastness, and fulling properties, making it suitable for various textile applications.
Used in Analytical Chemistry:
ALIZARIN BLUE S is used as a colorimetric reagent in analytical chemistry for the detection and quantification of certain metal ions, such as calcium and magnesium, due to its color-changing properties in the presence of these ions.
Used in Biological Staining:
ALIZARIN BLUE S is used as a biological stain for the visualization of specific cellular structures, such as bone and cartilage, due to its affinity for calcium and other minerals. Its color-changing properties also allow for the differentiation of live and dead cells in certain applications.

Check Digit Verification of cas no
The CAS Registry Mumber 66675-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,7 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66675-89:
(7*6)+(6*6)+(5*6)+(4*7)+(3*5)+(2*8)+(1*9)=176
176 % 10 = 6
So 66675-89-6 is a valid CAS Registry Number.
