Dianhydrostrophanthidin, also known as DAS, is a naturally occurring cardiac glycoside derived from the plant Strophanthus kombé. It is structurally similar to the well-known cardiac glycoside digoxin, and like other cardiac glycosides, it has the ability to inhibit the sodium-potassium ATPase enzyme, which plays a crucial role in the regulation of the heart's electrical activity and contractility. This inhibition leads to an increase in the intracellular sodium concentration, which in turn affects the calcium levels, ultimately leading to a positive inotropic effect on the heart, meaning it strengthens the heart muscle's contractions. Dianhydrostrophanthidin has been used in traditional medicine for its potential benefits in treating heart conditions, although its use is limited due to its narrow therapeutic index and the availability of safer alternatives. It is important to note that the use of Dianhydrostrophanthidin should be under the supervision of a healthcare professional due to its potential toxicity.
The CAS Registry Mumber 6785-67-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,8 and 5 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6785-67: (6*6)+(5*7)+(4*8)+(3*5)+(2*6)+(1*7)=137 137 % 10 = 7 So 6785-67-7 is a valid CAS Registry Number.
