17α-Bromethinyl-3-methoxy-1,3,5(10)-oestratrien-17β-ol, also known as bromocriptine, is a semi-synthetic ergot alkaloid derivative that acts as a dopamine agonist. It is primarily used in the treatment of various hormonal disorders, including Parkinson's disease, acromegaly, and hyperprolactinemia. Bromocriptine works by stimulating dopamine receptors in the brain, which helps to regulate hormone production and alleviate symptoms associated with these conditions. The chemical structure of bromocriptine features a bromoethinyl group at the 17α position, a methoxy group at the 3 position, and an oestratrien core with a 17β-ol functional group. Its therapeutic effects are attributed to its ability to modulate dopamine signaling, making it a valuable tool in the management of certain endocrine and neurological disorders.
The CAS Registry Mumber 4652-89-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,5 and 2 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4652-89: (6*4)+(5*6)+(4*5)+(3*2)+(2*8)+(1*9)=105 105 % 10 = 5 So 4652-89-5 is a valid CAS Registry Number.
