The chemical structure of "(3beta,5alpha,6beta,10alpha)-5-bromo-3-hydroxy-6,19-epoxypregnan-20-one" suggests it may have biological activities and potential pharmaceutical applications, although further research is needed to fully understand its properties and potential uses.
Check Digit Verification of cas no
The CAS Registry Mumber 5563-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,6 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5563-20:
(6*5)+(5*5)+(4*6)+(3*3)+(2*2)+(1*0)=92
92 % 10 = 2
So 5563-20-2 is a valid CAS Registry Number.
