2H-Tetrazolium, 5-(4-nitrophenyl)-2,3-diphenyl-, bromide, also known as MTT, is a yellow tetrazolium salt commonly used in biological assays to measure cell viability and proliferation. It is reduced by mitochondrial dehydrogenases in living cells to form a purple formazan product, which can be quantified by measuring the absorbance at 570 nm. This chemical is particularly useful in assessing the cytotoxicity of drugs, toxins, or other substances on cell cultures, as well as in monitoring the growth and health of cells over time. The bromide salt form of MTT is often preferred for its solubility and stability in aqueous solutions, making it a popular choice in various research applications.

6165-62-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6165-62-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,6 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6165-62:
(6*6)+(5*1)+(4*6)+(3*5)+(2*6)+(1*2)=94
94 % 10 = 4
So 6165-62-4 is a valid CAS Registry Number.
