298-95-3 Usage

Uses

Used in Microbiology:
Neotetrazolium chloride is used as a staining agent for microorganisms, allowing for the identification and differentiation of living cells from dead cells. This is particularly useful in the study of bacterial growth and activity.
Used in Histology and Cytochemistry:
In the fields of histology and cytochemistry, Neotetrazolium chloride is used as a staining agent for plant and animal tissues. It aids in the visualization of cellular structures and the detection of specific enzymes, such as dehydrogenases, which play a crucial role in various cellular processes.
Used in Enzyme Assays:
Neotetrazolium chloride is also utilized in the determination of amylase, an enzyme that breaks down starch into sugars. By using Neotetrazolium chloride, researchers can accurately measure the activity of amylase in various samples, which can be valuable in diagnosing and studying conditions related to carbohydrate metabolism.

Check Digit Verification of cas no

The CAS Registry Mumber 298-95-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 298-95:
(5*2)+(4*9)+(3*8)+(2*9)+(1*5)=93
93 % 10 = 3
So 298-95-3 is a valid CAS Registry Number.
