Benzaldehyde dipropargyl acetal, also known as 1,1-diethoxynon-1-yn-3-ol, is a colorless liquid organic compound with the chemical formula C12H18O2. It is derived from benzaldehyde and serves as a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. This acetal is formed by the reaction of benzaldehyde with two equivalents of propargyl alcohol in the presence of an acid catalyst, resulting in a stable compound that can be used in various chemical transformations. Benzaldehyde dipropargyl acetal is known for its ability to protect the aldehyde group and can be selectively deprotected under mild conditions, making it a useful building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 2188-14-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,8 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2188-14:
(6*2)+(5*1)+(4*8)+(3*8)+(2*1)+(1*4)=79
79 % 10 = 9
So 2188-14-9 is a valid CAS Registry Number.
