(R,S/S,R)-3-Brom-2-methyl-1,3-diphenyl-1-propanon is a chiral organic compound characterized by the presence of a bromine atom at the 3-position, a methyl group at the 2-position, and two phenyl rings attached to the 1 and 3 positions. (R,S/S,R)-3-Brom-2-methyl-1,3-diphenyl-1-propanon exhibits stereoisomerism, with the R,S and S,R configurations referring to the arrangement of substituents around the chiral centers. The compound is a derivative of 1,3-diphenylpropanone, with the addition of a bromine atom and a methyl group altering its chemical properties. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals, and its chiral nature makes it a subject of interest in the field of asymmetric synthesis and enantioselective catalysis.

Check Digit Verification of cas no

The CAS Registry Mumber 81788-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,8 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81788-80:
(7*8)+(6*1)+(5*7)+(4*8)+(3*8)+(2*8)+(1*0)=169
169 % 10 = 9
So 81788-80-9 is a valid CAS Registry Number.

Structure and Stereochemistry of the Dehydrobromination of some β-Bromo Ketones Derived from Alkyl Phenyl Ketones and Benzaldehyde

Quast, Helmut,Mueller, Bodo,Peters, Karl,Schnering, Hans Georg von

, p. 1525 - 1546 (2007/10/02)

The aldol reaction of alkyl phenyl ketones with benzaldehyde in the presence of hydrogen bromide affords diastereomeric β-bromo ketones under thermodynamic control.Thus, from propiophenone (8a) two diastereomeres 9a are obtained in a 67 : 33 ratio, while
