17α-Methyl-9,10-seco-B-norandrosta-1,3,5-trien-3,4,9β,17β-tetrol is a complex organic compound with the molecular formula C21H32O4. It is a synthetic steroid derived from the androstane family, characterized by the presence of a methyl group at the 17α position and a seco-B-nor structure, which means it has a broken carbon-carbon bond between carbons 9 and 10. 17α-Methyl-9,10-seco-B-norandrosta-1,3,5-trien-3,4,9β,17β-tetrol features a tricyclic structure with three hydroxyl groups at the 3, 9β, and 17β positions, and a double bond between carbons 1 and 3, as well as between carbons 4 and 5. Due to its unique structure, it exhibits specific biological activities and is often used in pharmaceutical research to study the effects of steroidal compounds on various physiological processes.
The CAS Registry Mumber 7635-80-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 5 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7635-80: (6*7)+(5*6)+(4*3)+(3*5)+(2*8)+(1*0)=115 115 % 10 = 5 So 7635-80-5 is a valid CAS Registry Number.
