66794-29-4 Usage
General Description
1-Butynyl iodide is a chemical compound with the formula C4H5I. It is a colorless to pale yellow liquid that is primarily used as an intermediate in organic synthesis. 1-BUTYNYL IODIDE is commonly used as a reagent for preparing other organic compounds, particularly in the synthesis of pharmaceuticals and agrochemicals. Its properties as a reactive alkylating agent make it useful in a variety of chemical reactions, particularly in the formation of carbon-carbon bonds. While it is a versatile compound with many potential applications, it is important to handle 1-butynyl iodide with care due to its reactive and potentially hazardous nature.
Check Digit Verification of cas no
The CAS Registry Mumber 66794-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,7,9 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 66794-29:
(7*6)+(6*6)+(5*7)+(4*9)+(3*4)+(2*2)+(1*9)=174
174 % 10 = 4
So 66794-29-4 is a valid CAS Registry Number.
