Uses
9β,11β-Epoxy-21dehydroxy betamethasone is synthesized from 9β,11β-epoxy-17,21-dihydroxy-16β-methylpregna-1,4-diene-3,20-dione (E589175), which is a metabolite of momestasone furoate (M490000).
Check Digit Verification of cas no
The CAS Registry Mumber 37413-99-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,4,1 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 37413-99:
(7*3)+(6*7)+(5*4)+(4*1)+(3*3)+(2*9)+(1*9)=123
123 % 10 = 3
So 37413-99-3 is a valid CAS Registry Number.
