Check Digit Verification of cas no

The CAS Registry Mumber 154675-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,6,7 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 154675-20:
(8*1)+(7*5)+(6*4)+(5*6)+(4*7)+(3*5)+(2*2)+(1*0)=144
144 % 10 = 4
So 154675-20-4 is a valid CAS Registry Number.

Synthetic studies toward c-glucosidic ellagitannins: A biomimetic total synthesis of 5-O-desgalloylepipunicacortein A

Malik, Ga?lle,Natangelo, Anna,Charris, Jaime,Pouységu, Laurent,Manfredini, Stefano,Cavagnat, Dominique,Buffeteau, Thierry,Deffieux, Denis,Quideau, Stéphane

, p. 9063 - 9074 (2012/10/07)

C-glucosidic ellagitannins constitute a subclass of bioactive polyphenolic natural products with strong antioxidant properties, as well as promising antitumoral and antiviral activities that are related to their capacity to interact with both functional and structural proteins. To date, most synthetic efforts toward ellagitannins have concerned glucopyranosic species. The development of a synthetic strategy to access C-glucosidic ellagitannins, whose characteristic structural feature includes an atropoisomeric hexahydroxydiphenoyl (HHDP) or a nonahydroxyterphenoyl (NHTP) unit that is linked to an open-chain glucose core by a C-aryl glucosidic bond, is described herein. The total synthesis of the biarylic HHDP-containing 5-O- desgalloylepipunicacortein A (1 β) was achieved by either using the natural ellagic acid bis-lactone as a precursor of the requested HHDP unit or by implementing an atroposelective intramolecular oxidative biarylic coupling to forge this HHDP unit. Both routes converged in the penultimate step of this synthesis to enable a biomimetic formation of the key C-aryl glucosidic bond in the title compound.

New hexahydroxybiphenyl derivatives as inhibitors of protein kinase C

Kashiwada,Huang,Ballas,Jiang,Janzen,Lee

, p. 195 - 200 (2007/10/02)

We have previously shown that some ellagitannins are potent inhibitors of protein kinase C (PKC). On the basis of this finding, several series of hexahydroxybiphenyl derivatives of ellagic acid were synthesized as simple analogs of these ellagitannins and were evaluated for their inhibitory effect against PKC. Compounds 23 and 26 were found to be potent inhibitors of PKC, while hexakis(benzyloxy)biphenyl derivatives exhibited weak anti-PKC activity.
