Zinc, bromo-2-propynyl-, also known as zinc 2-bromopropynyl or zinc bromoacetylide, is an organozinc compound with the chemical formula Zn(C≡CCH2Br)2. It is a colorless to pale yellow solid that is sensitive to air and moisture. Zinc, bromo-2-propynyl- is primarily used as a reagent in organic synthesis, particularly in the preparation of various organic compounds through coupling reactions. It is synthesized by reacting zinc dust with 2-bromopropyne in an inert solvent, such as tetrahydrofuran or diethyl ether. Due to its reactivity, it is essential to handle zinc, bromo-2-propynyl- with care and store it under an inert atmosphere to prevent decomposition.

40963-57-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40963-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,6 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40963-57:
(7*4)+(6*0)+(5*9)+(4*6)+(3*3)+(2*5)+(1*7)=123
123 % 10 = 3
So 40963-57-3 is a valid CAS Registry Number.
