1-(Ethynyloxy)butane, also known as 4-butyn-1-ol or but-4-yn-1-ol, is a colorless liquid organic compound with the chemical formula C6H10O. It is characterized by the presence of a butyn-1-ol functional group, which consists of a four-carbon chain with a triple bond between the second and third carbon atoms, and a hydroxyl group attached to the first carbon atom. This molecule is an important intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. Due to its reactivity, 1-(ethynyloxy)butane is often used in chemical reactions involving the formation of new carbon-carbon bonds, such as in the preparation of acetylenic esters and other related compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 3329-56-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,2 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3329-56:
(6*3)+(5*3)+(4*2)+(3*9)+(2*5)+(1*6)=84
84 % 10 = 4
So 3329-56-4 is a valid CAS Registry Number.
