18045-83-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 18045-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,4 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18045-83:
(7*1)+(6*8)+(5*0)+(4*4)+(3*5)+(2*8)+(1*3)=105
105 % 10 = 5
So 18045-83-5 is a valid CAS Registry Number.

Stereo-controlled Alkylation of Cyclodecadienone Derivatives and the Total Synthesis of (-)- and (+)-4,5-cis-3β-Hydroxygermacranolides

Nakamura, Takayoshi,Hirota, Hiroshi,Kuroda, Chiaki,Takahashi, Takeyoshi

, p. 1879 - 1882 (2007/10/02)

Direct trapping of the intermediate, produced by anionic oxy-Cope rearrangement of (1S,4S,6S)-4-alkoxy-1-ethenyl-3-methyl-6-(1-methylethenyl)-2-cyclohexen-1-ol, with ethyl bromoacetate gave ethyl -3-alkoxy-6-oxo-13-nor-1(10),4-germacradien-12-oate stereoselectively, which was converted into a natural (-)-4,5-cis-3β-hydroxygermacranolide.
