Δ11-Pregnendion-3,20, also known as 11-deoxycortisol, is a steroid hormone that belongs to the class of pregnanes. It is a precursor in the biosynthesis of various corticosteroids, including cortisol, aldosterone, and cortisone. Δ11-Pregnendion-3,20 plays a crucial role in the regulation of metabolism, immune response, and stress in the body. Δ11-Pregnendion-3,20 is synthesized in the adrenal cortex from cholesterol through a series of enzymatic reactions. It is an important intermediate in the steroidogenic pathway and is converted to other biologically active steroids by specific enzymes. The study of Δ11-Pregnendion-3,20 is essential for understanding the mechanisms of steroid hormone synthesis and their physiological effects.
The CAS Registry Mumber 26423-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,4,2 and 3 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 26423-80: (7*2)+(6*6)+(5*4)+(4*2)+(3*3)+(2*8)+(1*0)=103 103 % 10 = 3 So 26423-80-3 is a valid CAS Registry Number.
