Check Digit Verification of cas no

The CAS Registry Mumber 347840-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,8,4 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 347840-65:
(8*3)+(7*4)+(6*7)+(5*8)+(4*4)+(3*0)+(2*6)+(1*5)=167
167 % 10 = 7
So 347840-65-7 is a valid CAS Registry Number.

Total synthesis of the quinone epoxide dimer (+)-torreyanic acid: Application of a biomimetic oxidation/electrocyclization/Diels-Alder dimerization cascade

Li, Chaomin,Johnson, Richard P.,Porco Jr., John A.

, p. 5095 - 5106 (2007/10/03)

An asymmetric synthesis of the quinone epoxide dimer (+)-torreyanic acid (48) has been accomplished employing [4 + 2] dimerization of diastereomeric 2H-pyran monomers. Synthesis of the related monomeric natural product (+)-ambuic acid (2) has also been achieved which establishes the biosynthetic relationship between these two natural products. A tartrate-mediated nucleophilic epoxidation involving hydroxyl group direction facilitated the asymmetric synthesis of a key chiral quinone monoepoxide intermediate. Thermolysis experiments have also been conducted on a model dimer based on the torreyanic acid core structure and facile retro Diels-Alder reaction processes and equilibration of diastereomeric 2H-pyrans have been observed. Theoretical calculations of Diels-Alder transition states have been performed to evaluate alternative transition states for Diels-Alder dimerization of 2H-pyran quinone epoxide monomers and provide insight into the stereocontrol elements for these reactions.

Exploring Chemical Diversity of Epoxyquinoid Natural Products: Synthesis and Biological Activity of (-)-Jesterone and Related Molecules

Hu, Yongbo,Li, Chaomin,Kulkarni, Bheemashankar A.,Strobel, Gary,Lobkovsky, Emil,Torczynski, Richard M.,Porco Jr., John A.

, p. 1649 - 1652 (2007/10/03)

(matrix presented) Enantioselective syntheses of the potent antifungal agent (-)-jesterone, its hydroxy epimer, and a dimeric quinone epoxide derivative are reported. The synthesis involves diastereoselective epoxidation of a chiral quinone monoketal deri
