Bromo-penta-2,4-dienyl-zinc, also known as 1-bromo-2,4-pentadienylzinc bromide, is an organozinc reagent used in organic synthesis. It is a colorless to pale yellow liquid and is highly sensitive to air and moisture. bromo-penta-2,4-dienyl-zinc is generated by the reaction of 1-bromo-2,4-pentadienyl bromide with zinc metal in a THF solvent. Bromo-penta-2,4-dienyl-zinc is a useful building block for the synthesis of various organic compounds, particularly in the formation of carbon-carbon bonds through cross-coupling reactions. It is also employed in the preparation of conjugated dienes and other complex organic molecules. Due to its reactivity, it is crucial to handle bromo-penta-2,4-dienyl-zinc under an inert atmosphere, such as nitrogen or argon, to prevent unwanted side reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 929-03-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,2 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 929-03:
(5*9)+(4*2)+(3*9)+(2*0)+(1*3)=83
83 % 10 = 3
So 929-03-3 is a valid CAS Registry Number.
