90295-64-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90295-64-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,9 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 90295-64:
(7*9)+(6*0)+(5*2)+(4*9)+(3*5)+(2*6)+(1*4)=140
140 % 10 = 0
So 90295-64-0 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.
