16α-hydroxy-3-methoxy-estra-1,3,5(10)-trien-17-one is a naturally occurring steroidal compound derived from the plant Dioscorea nipponica. It belongs to the class of steroidal saponins, which are known for their diverse biological activities. This specific compound features a hydroxyl group at the 16α position and a methoxy group at the 3 position, attached to a steroidal framework with a 17-ketone group. The structure is characterized by three double bonds in the A, B, and D rings, which contribute to its unique chemical properties. Research on such compounds is important due to their potential applications in medicine and pharmacology, as they may exhibit various therapeutic effects. However, further studies are needed to fully understand their mechanisms of action and potential uses.
The CAS Registry Mumber 3434-77-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,3 and 4 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 3434-77: (6*3)+(5*4)+(4*3)+(3*4)+(2*7)+(1*7)=83 83 % 10 = 3 So 3434-77-3 is a valid CAS Registry Number.
