11β-Hydroxy-3-keto-4-androstene-17β-carboxylic acid, also known as 11-hydroxyprogesterone or 11-OH-progesterone, is a steroid hormone derived from progesterone. It plays a crucial role in the synthesis of other important hormones, such as cortisol and aldosterone, and is involved in the regulation of various physiological processes, including stress response, immune function, and electrolyte balance. This chemical is a key intermediate in the biosynthesis of glucocorticoids and mineralocorticoids, which are essential for maintaining homeostasis in the body. The structure of 11β-hydroxy-3-keto-4-androstene-17β-carboxylic acid consists of a four-ring steroid nucleus with a hydroxyl group at the 11β position, a ketone group at the 3 position, and a carboxylic acid group at the 17β position.
The CAS Registry Mumber 7323-96-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,2 and 3 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 7323-96: (6*7)+(5*3)+(4*2)+(3*3)+(2*9)+(1*6)=98 98 % 10 = 8 So 7323-96-8 is a valid CAS Registry Number.
