5-Hydroxy-6-methoxy-2-methyl-indole-3-carboxylic acid ethyl ester, also known as psilocybin, is a naturally occurring psychedelic compound found in certain species of mushrooms. It is an indole alkaloid that belongs to the tryptamine family, characterized by its unique chemical structure, which includes a hydroxyl group at the 5th position, a methoxy group at the 6th position, a methyl group at the 2nd position, and an ethyl ester group attached to the carboxylic acid at the 3rd position. Psilocybin is known for its psychoactive properties, which are attributed to its ability to bind to serotonin receptors in the brain, leading to altered perceptions, mood, and cognitive effects. It has been the subject of scientific research for its potential therapeutic applications in treating various mental health conditions, such as depression and anxiety.
The CAS Registry Mumber 5165-43-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 5 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5165-43: (6*5)+(5*1)+(4*6)+(3*5)+(2*4)+(1*3)=85 85 % 10 = 5 So 5165-43-5 is a valid CAS Registry Number.
