Cis-1-brom-1,2-difluor-pent-1-en-3-in, also known as (Z)-1-bromo-1,2-difluoropent-1-en-3-yne, is a halogenated alkyne with the molecular formula C5H4BrF2. This organic compound features a pent-1-en-3-yne backbone, with a bromine atom attached to the first carbon, and two fluorine atoms bonded to the second carbon. The "cis" configuration indicates that the bromine and fluorine atoms are on the same side of the double bond. This chemical is of interest in organic synthesis and may have potential applications in the development of pharmaceuticals or specialty chemicals due to its unique structure and reactivity.
The CAS Registry Mumber 2546-53-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 6 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2546-53: (6*2)+(5*5)+(4*4)+(3*6)+(2*5)+(1*3)=84 84 % 10 = 4 So 2546-53-4 is a valid CAS Registry Number.
