General Description
1-Phenyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole is a chemical compound that belongs to the group of organoboron compounds, which are characterized by the presence of boric acid in their molecular structure. It is also part of the pyrazoles family, which contains a five-membered ring of three carbon atoms and two nitrogen atoms. 1-Phenyl-3-(4,4,5,5-tetraMethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole can be used in various chemical reactions, most notably the Suzuki-Miyaura cross-coupling reaction, which is extensively used in organic chemistry to form carbon-carbon bonds. Overall, this chemical is an important reactive tool in the field of synthetic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 1002334-13-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,2,3,3 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1002334-13:
(9*1)+(8*0)+(7*0)+(6*2)+(5*3)+(4*3)+(3*4)+(2*1)+(1*3)=65
65 % 10 = 5
So 1002334-13-5 is a valid CAS Registry Number.

(Chemical Equation Presented) From dipole to diazole! A direct and regioselective route to functionalized pyrazole boronic esters is developed that employs the cycloaddition of alkynylboronates with sydnones. Functionalization of these products by Suzuki coupling and N-deprotection processes highlight the potential synthetic utility of these species.
