18318-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18318-53-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,3,1 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18318-53:
(7*1)+(6*8)+(5*3)+(4*1)+(3*8)+(2*5)+(1*3)=111
111 % 10 = 1
So 18318-53-1 is a valid CAS Registry Number.

The total synthesis of (+)-cyperolone, an eudesmane-derived sesquiterpenoid from Cyperus rotundus, is described. The de novo synthesis was accomplished via a 15 step sequence starting from (R)-(-)-carvone. The synthetic route features a platinum-catalyzed
