1400-62-0 Usage
Description
Orcein, also known as C.I. 73000, is a weakly acidic orange-red fluorochrome belonging to the class of benzofurans. It is primarily used for staining elastic tissue and, in acidic solutions, can also stain basophilic chromosomes purple-red. Orcein is an organic dye and histochemical stain, known for its dark brown crystalline or powder form.
Uses
Used in Biological Staining:
Orcein is used as a biological stain for the identification and visualization of specific cellular structures, particularly elastic tissue. Its staining properties make it a valuable tool in histology and cytology.
Used in Extracellular Matrix Staining:
Orcein is also utilized as a stain for extracellular matrices, aiding in the examination of the structural components of connective tissues.
Used in Dyes and Metabolites:
Orcein's dye properties extend its applications to various fields, including the staining of dyes and metabolites for research and analysis purposes.
Check Digit Verification of cas no
The CAS Registry Mumber 1400-62-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,0 and 0 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1400-62:
(6*1)+(5*4)+(4*0)+(3*0)+(2*6)+(1*2)=40
40 % 10 = 0
So 1400-62-0 is a valid CAS Registry Number.
