1400-62-0 Usage

Chemical Properties

dark brown crystals or powder

Uses

Different sources of media describe the Uses of 1400-62-0 differently. You can refer to the following data:
1. Biological stain.
2. Orcein (cas# 1400-62-0) is an organic dye and histochemical stain. Orcein has also been used as a stain for extracellular matrices. Dyes and metabolites.

Definition

ChEBI: A member of the class of benzofurans that is dibenzo[b,d]furan-3,7-dione bearing two methyl substituents at positions 1 and 9 as well as two 2,4-dihydroxy-6-methylanilino substituents at positions 2 and 8.

General Description

Orcein is a weakly acidic orange-red fluorochrome and is mainly required for the staining of elastic tissue. It is not specific for chromatin staining, however, in acidic solutions it works as a basic dye and stains basophilic chromosomes purple red.

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.
