1264-32-0 Usage
General Description
Disodium 4,4'-bis[[6-anilino-1,4-dihydro-4-oxo-1,3,5-triazin-2-yl]amino]stilbene-2,2′-disulphonate, also known as DAPI, is a fluorescent dye commonly used in biology and biochemistry for staining nuclei in fluorescence microscopy and cytometry. Its chemical structure consists of two aniline groups connected to a central triazine ring, which is further attached to a stilbene backbone and two sulfonate groups. The compound exhibits strong blue fluorescence when bound to DNA, making it a valuable tool for visualizing cellular and nuclear structures. DAPI is also widely used in research for studying the dynamics and organization of chromatin in live cells, as well as for cell cycle analysis and DNA quantification. Additionally, DAPI has applications in the field of immunohistochemistry and in the staining of bacteria and yeast cells.
Check Digit Verification of cas no
The CAS Registry Mumber 1264-32-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,6 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1264-32:
(6*1)+(5*2)+(4*6)+(3*4)+(2*3)+(1*2)=60
60 % 10 = 0
So 1264-32-0 is a valid CAS Registry Number.
