Zinc, butyliodo-, also known as butylzinc or n-butylzinc, is an organozinc compound with the chemical formula C4H9Zn. It is a colorless, volatile, and highly reactive liquid that is sensitive to air and moisture. Butylzinc is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Negishi coupling reaction. It is also employed as a reducing agent and a catalyst in various chemical processes. Due to its high reactivity, butylzinc must be handled with extreme caution, typically under an inert atmosphere or in a glovebox, to prevent unwanted side reactions and potential hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 34219-54-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,1 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 34219-54:
(7*3)+(6*4)+(5*2)+(4*1)+(3*9)+(2*5)+(1*4)=100
100 % 10 = 0
So 34219-54-0 is a valid CAS Registry Number.
