"16α,17α-Epoxypregn-5-en-3β-ol-20-one ethoxycarbonylhydrazone" is a complex organic compound with a molecular formula of C25H35NO4. It is a derivative of pregnane, a steroid with a pregnane skeleton, which is characterized by a fused ring structure of three six-membered rings and one five-membered ring. The compound features a 16α,17α-epoxy group, indicating the presence of an epoxy ring between carbons 16 and 17. It also has a 5-en group, which is a double bond between carbons 5 and 6, and a 3β-ol hydroxyl group, which is a hydroxyl group attached to carbon 3 in the β-configuration. The 20-one indicates a ketone group at the 20th carbon. The ethoxycarbonylhydrazone part of the name suggests that the compound has been modified with an ethoxycarbonyl group and a hydrazone moiety, which are often used in chemical synthesis to protect certain functional groups or to facilitate reactions. 16α,17α-Epoxypregn-5-en-3β-ol-20-one ethoxycarbonylhydrazone is likely used in pharmaceutical or chemical research due to its structural complexity and potential reactivity.
The CAS Registry Mumber 2543-06-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2543-06: (6*2)+(5*5)+(4*4)+(3*3)+(2*0)+(1*6)=68 68 % 10 = 8 So 2543-06-8 is a valid CAS Registry Number.
