5α-Pregnan-20β-ol, also known as pregnanolone, is a naturally occurring steroid hormone and a metabolite of progesterone. It plays a crucial role in the body's endocrine system and is involved in various physiological processes, including neurosteroidogenesis, which is the synthesis of steroids in the brain. Pregnanolone is known for its potent effects on the central nervous system, where it acts as a positive allosteric modulator of the GABA-A receptor, enhancing its inhibitory action and thus having sedative, anxiolytic, and anticonvulsant properties. Additionally, it is involved in the regulation of stress responses and may contribute to the maintenance of pregnancy. The compound is also of interest in medical research due to its potential therapeutic applications in treating certain neurological and psychiatric disorders.
The CAS Registry Mumber 796-20-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 6 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 796-20: (5*7)+(4*9)+(3*6)+(2*2)+(1*0)=93 93 % 10 = 3 So 796-20-3 is a valid CAS Registry Number.
