1249-97-4 Usage
General Description
Benzoyl leuco methylene blue is a chemical compound commonly used as a reaction indicator in analytical chemistry. It is a derivative of methylene blue, a synthetic dye, and is often employed in redox titrations to detect the endpoint of a reaction. Benzoyl leuco methylene blue is a colorless, water-soluble compound that can undergo a reversible reaction with oxygen, causing it to turn blue in the presence of oxidizing agents. This makes it a valuable tool for determining the concentration of certain compounds in a sample solution, as well as for monitoring the progress of chemical reactions. Overall, benzoyl leuco methylene blue serves as a reliable and efficient indicator in a variety of chemical and analytical applications.
Check Digit Verification of cas no
The CAS Registry Mumber 1249-97-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1249-97:
(6*1)+(5*2)+(4*4)+(3*9)+(2*9)+(1*7)=84
84 % 10 = 4
So 1249-97-4 is a valid CAS Registry Number.
