6274-20-0 Usage
General Description
Sodium m-toluidinomethanesulphonate, also known as Toluidine blue O, is a chemical compound commonly used as a biological stain in histology and cytology. It is a basic dye that binds to negatively charged molecules such as nucleic acids and proteins, allowing them to be easily visualized under a microscope. This chemical is commonly used to stain tissues for the examination of cell morphology and structure in medical and research settings. Additionally, it is used in the textile industry as a dye, in the semiconductor industry as a photoresist, and in the water treatment industry as a detector for sulfite. Sodium m-toluidinomethanesulphonate is considered toxic and should be handled with care and proper safety precautions.
Check Digit Verification of cas no
The CAS Registry Mumber 6274-20-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6274-20:
(6*6)+(5*2)+(4*7)+(3*4)+(2*2)+(1*0)=90
90 % 10 = 0
So 6274-20-0 is a valid CAS Registry Number.
