85428-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85428-14-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,4,2 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 85428-14:
(7*8)+(6*5)+(5*4)+(4*2)+(3*8)+(2*1)+(1*4)=144
144 % 10 = 4
So 85428-14-4 is a valid CAS Registry Number.

Total Synthesis of (+/-)-Cycloeudesmol and (+/-)- Epicycloeudesmol
Chen, Edward Y.
, p. 3245 - 3250 (2007/10/02)
The first total synthesis of both (+/-)-cycloeudesmol (3) and (+/-)-epicycloeudesmol (4) is described.The key stereospecific construction of the bicyclohexane system was conveniently achieved by an olefin-ketocarbene cyclization reaction.
