601-03-6 Usage
General Description
The chemical compound "3beta,17,21-trihydroxy-5beta-pregnan-20-one" is a steroid hormone and a metabolite of the hormone progesterone. It is also known as 20-dihydroprogesterone and is produced in the body as part of the normal metabolism of progesterone. 3beta,17,21-trihydroxy-5beta-pregnan-20-one has been found to have neuroprotective and anti-inflammatory properties, and it has been suggested to play a role in the regulation of the central nervous system. It is also being studied for its potential therapeutic applications in conditions such as traumatic brain injury, multiple sclerosis, and other neurological disorders.
Check Digit Verification of cas no
The CAS Registry Mumber 601-03-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 601-03:
(5*6)+(4*0)+(3*1)+(2*0)+(1*3)=36
36 % 10 = 6
So 601-03-6 is a valid CAS Registry Number.
