CTC, or 5-Cyano-2,3-di-(p-tolyl)tetrazolium (chloride), is a redox-sensitive tetrazolium salt primarily used to detect metabolic activity in microorganisms. It is a membrane-permeable indicator that is readily taken up by living cells and reduced by respiratory activity to produce a red fluorescent, water-insoluble formazan crystal.

90217-02-0 Usage

Uses

Used in Microbiology:
CTC is used as a vital stain for actively respiring bacteria, serving as a cellular indicator of respiratory activity in cells, especially for tracking P450 activity.
Used in Flow Cytometry:
CTC is used as a redox dye in flow cytometry, with an excitation laser at 480 nm and detection in the red region, to evaluate the metabolic activity of cells.

Check Digit Verification of cas no

The CAS Registry Mumber 90217-02-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,1 and 7 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90217-02:
(7*9)+(6*0)+(5*2)+(4*1)+(3*7)+(2*0)+(1*2)=100
100 % 10 = 0
So 90217-02-0 is a valid CAS Registry Number.
