Check Digit Verification of cas no
The CAS Registry Mumber 452085-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,0,8 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 452085-65:
(8*4)+(7*5)+(6*2)+(5*0)+(4*8)+(3*5)+(2*6)+(1*5)=143
143 % 10 = 3
So 452085-65-3 is a valid CAS Registry Number.

[reaction: see text] Natural 6-epiplakortolide E was first synthesized from readily available 1-bromo-10-phenyldecane in 10 steps by using singlet oxygen-mediated Diels-Alder reaction to form cyclic peroxide followed by a directed iodolactonization to give the peroxylactone core.
