71769-53-4 Usage
General Description
Potassium hydroxide, also known as caustic potash, is a powerful base and strong alkali used in several industrial and manufacturing processes. Its chemical formula is KOH, and it is often found in the form of white, hygroscopic pellets or flakes. Potassium hydroxide is commonly used in the production of various chemicals, soaps, and detergents, as well as in the manufacturing of batteries, fertilizers, and pharmaceuticals. It is also used in the production of biodiesel and as a chemical reagent in laboratories. Potassium hydroxide is highly corrosive and can cause severe burns upon contact with skin, making it important to handle this chemical with care and appropriate safety precautions.
Check Digit Verification of cas no
The CAS Registry Mumber 71769-53-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,6 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71769-53:
(7*7)+(6*1)+(5*7)+(4*6)+(3*9)+(2*5)+(1*3)=154
154 % 10 = 4
So 71769-53-4 is a valid CAS Registry Number.

Study of the chemiluminescent reaction between alkali dimers and oxygen atoms
Figger, H.,Straubinger, R.,Walther, H.
, p. 179 - 185 (2007/10/02)
The reaction of alkali dimers with oxygen atoms has been studied in a crossed beam experiment.Strong chemiluminescence of the reaction products was observed.It is shown that the luminescence was emitted by alkali from the reaction M2+O->MO+M* (M alkali atom).M* can be excited up to exoergicity of this reaction at least in the cases M=Cs and Na.For M=Cs, detailed rate constants for the excitation of the different excited states have been determined using both laser induced fluorescence and chemiluminescence.The rates decrease nearly exponentially as a function of the excitation energy.They partly follow the expectation of statistical theories.Absolute reaction cross sections have been determined for all of the reactions investigated.They agree partially with those predicted by the harpoon model.
