(+/-)-3-<2-Isopropyl-3-methyl-phenoxy>-butan-2-on, also known as carvedilol, is a non-selective beta-blocker and vasodilator chemical compound with the molecular formula C24H26N2O4. It is primarily used in the treatment of hypertension, heart failure, and left ventricular dysfunction following a myocardial infarction. Carvedilol works by blocking the action of certain hormones and neurotransmitters, which helps to lower blood pressure and reduce the workload on the heart. The chemical structure of carvedilol consists of a butyrophenone core with a 2-isopropyl-3-methyl-phenoxy group attached to the third carbon, and a 1,4-dihydro-2H-3,1-benzoxazine-2-one ring system. It is a racemic mixture, meaning it contains equal amounts of both the R and S enantiomers.
The CAS Registry Mumber 1680-61-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 0 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1680-61: (6*1)+(5*6)+(4*8)+(3*0)+(2*6)+(1*1)=81 81 % 10 = 1 So 1680-61-1 is a valid CAS Registry Number.
