514-21-6 Usage
General Description
3beta,14,16beta-trihydroxy-5beta-card-20(22)-enolide 16-formate is a chemical compound with an intricate structure involving a steroid backbone. It contains three hydroxyl groups at the 3rd, 14th, and 16th carbon positions of the steroid ring, and features a formate group at the 16th position. 3beta,14,16beta-trihydroxy-5beta-card-20(22)-enolide 16-formate is also known as digoxin-16-formate, and is related to the cardiac glycoside family. Cardiac glycosides have been used for the treatment of heart conditions for centuries, and they work by increasing the contractility of the heart muscle. Digoxin-16-formate has potential pharmacological applications, particularly in the field of cardiology, and further research into its properties and effects may lead to new developments in the treatment of heart disease.
Check Digit Verification of cas no
The CAS Registry Mumber 514-21-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 4 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 514-21:
(5*5)+(4*1)+(3*4)+(2*2)+(1*1)=46
46 % 10 = 6
So 514-21-6 is a valid CAS Registry Number.

Cardiac Glycosides. 6. Gitoxigenin C16 Acetates, Formates, Methoxycarbonates, and Digitoxosides. Synthesis and Na+, K+ -ATPase Inhibitory Activities

A series of 17 gitoxigenin 16β-formates, acetates, and methoxycarbonates was synthesized, including their 3β-acetates, formates, and digitoxosides.A 16β-formate group was generally found to increase activity 30 times, a 16β-acetate group 9-12 times, while a 16β-methoxycarbonate decreased activity by two-thirds. 3β-Formates and acetates had little effect on activity by themselves, but sometimes reduced the activity-increasing properties of 16β-formates and acetates.A 3β-digitoxoside increases the activity of ditoxigenin by 15 times, but the effect is less ifthe 16β-group is esterified.And finally, a 16-one decreases activity dramatically.These data suggest an important role for C16 esters and possibly the presence of a separate binding site on Na+, K+ -ATPase corresponding to the cardenolide C16 position.
