81666-87-7 Usage
General Description
1,1',3,3,3',3'-Hexamethylindodicarbocyanine perchlorate, also known as DiD perchlorate, is a fluorescent dye commonly used for cell labeling and tracking. It is a carbocyanine dye with six methyl groups attached to the indodicarbocyanine core, giving it high stability and solubility in organic solvents. DiD perchlorate is widely utilized in biomedical research for applications such as flow cytometry, live cell imaging, and fluorescence microscopy. Its near-infrared emission makes it particularly useful for deep tissue imaging and in vivo studies. The dye is also used in diagnostics and drug delivery systems due to its excellent photostability and low cytotoxicity.
Check Digit Verification of cas no
The CAS Registry Mumber 81666-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,6 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81666-87:
(7*8)+(6*1)+(5*6)+(4*6)+(3*6)+(2*8)+(1*7)=157
157 % 10 = 7
So 81666-87-7 is a valid CAS Registry Number.
