Propadienylboronic acid dibutyl ester, also known as 1,3-butadienylboronic acid dibutyl ester, is an organic compound with the chemical formula C10H17BO2. It is a colorless liquid that is soluble in organic solvents and is used as an intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and agrochemicals. propadienylboronic acid dibutyl ester is characterized by its conjugated diene system, which allows for a range of chemical reactions, including addition reactions across the double bonds. It is also known for its reactivity with electrophiles due to the presence of the boronic acid group, which can participate in Suzuki coupling reactions, a type of carbon-carbon bond-forming reaction. Propadienylboronic acid dibutyl ester is typically handled with care due to its potential reactivity and sensitivity to air and moisture.

Check Digit Verification of cas no

The CAS Registry Mumber 6689-00-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6689-00:
(6*6)+(5*6)+(4*8)+(3*9)+(2*0)+(1*0)=125
125 % 10 = 5
So 6689-00-5 is a valid CAS Registry Number.
