Benzenepropanoic acid, R-(3-phenyl-2-propenylidene)-, also known as (R)-3-phenyl-2-propenylidenepropanoic acid, is a chiral organic compound with the molecular formula C12H12O2. It is a derivative of benzenepropanoic acid, featuring a 3-phenyl-2-propenylidene moiety attached to the propanoic acid backbone. Benzenepropanoic acid,R-(3-phenyl-2-propenylidene)- is characterized by its asymmetric carbon atom, which gives rise to two enantiomers: R and S configurations. It is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly those involving chiral molecules. The R-enantiomer, in particular, is often sought after due to its potential biological activity and selectivity in drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 5638-32-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,3 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5638-32:
(6*5)+(5*6)+(4*3)+(3*8)+(2*3)+(1*2)=104
104 % 10 = 4
So 5638-32-4 is a valid CAS Registry Number.
