Protiophenylacetylene, also known as 1-phenyl-1-propyne, is an organic compound with the chemical formula C9H8. It is a colorless liquid that is insoluble in water but soluble in organic solvents. protiophenylacetylene is characterized by a triple bond between the terminal carbon and the phenyl ring, which is a benzene ring. Protiophenylacetylene is an important building block in organic synthesis, particularly for the preparation of various phenylacetylene derivatives. It is used in the production of pharmaceuticals, agrochemicals, and materials such as polymers and conductive materials. The compound is synthesized through various methods, including the dehydrohalogenation of 1-iodo-1-phenylpropane or the coupling of phenylmagnesium bromide with propargyl bromide. Due to its reactivity, protiophenylacetylene is often used in cross-coupling reactions to form more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 696-51-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 696-51:
(5*6)+(4*9)+(3*6)+(2*5)+(1*1)=95
95 % 10 = 5
So 696-51-5 is a valid CAS Registry Number.
