Dibutyl-2,2-dicyan-cyclopropan-boronat, also known as dibutyl-2,2-dicyanocyclopropaneboronate, is a chemical compound with the molecular formula C13H20BN2. It is a white crystalline solid that is soluble in organic solvents. Dibutyl-2,2-dicyan-cyclopropan-boronat is primarily used as a reagent in organic synthesis, particularly in the formation of cyclopropane rings and as a source of the 2,2-dicyanocyclopropane anion. It is synthesized by the reaction of dibutylboron bromide with malononitrile in the presence of a base. Due to its reactivity, it is important to handle Dibutyl-2,2-dicyan-cyclopropan-boronat with care, typically under an inert atmosphere and at low temperatures to prevent decomposition.

Check Digit Verification of cas no
The CAS Registry Mumber 5271-83-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,7 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5271-83:
(6*5)+(5*2)+(4*7)+(3*1)+(2*8)+(1*3)=90
90 % 10 = 0
So 5271-83-0 is a valid CAS Registry Number.
