80326-84-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80326-84-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,2 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 80326-84:
(7*8)+(6*0)+(5*3)+(4*2)+(3*6)+(2*8)+(1*4)=117
117 % 10 = 7
So 80326-84-7 is a valid CAS Registry Number.

Quassinoids: Total Synthesis of dl-Castelanolide
Grieco, Paul A.,Lis, Randall,Ferrino, Sergio,Jaw,, John Yan
, p. 2342 - 2347 (2007/10/02)
The total synthesis of dl-castelanolide (5) is described, which proceeds in 15,2percent yield from the tetracyclic alcohol 8, thus confirming the structural assignment made via classical methods by Geissman over ten years ago.
