Check Digit Verification of cas no

The CAS Registry Mumber 39707-59-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,7,0 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 39707-59:
(7*3)+(6*9)+(5*7)+(4*0)+(3*7)+(2*5)+(1*9)=150
150 % 10 = 0
So 39707-59-0 is a valid CAS Registry Number.

Expediently Scalable Synthesis and Antifungal Exploration of (+)-Yahazunol and Related Meroterpenoids

Zhang, Shasha,Wang, Xia,Hao, Jin,Li, Dangdang,Csuk, René,Li, Shengkun

, p. 2010 - 2017 (2018/09/25)

The efficient synthesis and antifungal exploration of (+)-yahazunol and related natural products are described. Central to this strategy is the Barton decarboxylative coupling, comprising a one-pot radical decarboxylation and quinone addition cascade. The scalable synthesis of (+)-yahazunol was accomplished in five longest linear sequences (LLS) starting from commercially available and inexpensive (-)-sclareol. The divergent translational potential of (+)-yahazunol was demonstrated by the expedient preparation of (-)-zonarone, (-)-isozonarone, (-)-zonarol, (-)-isozonarol, (+)-chromazonarol, and (+)-yahazunone. This approach also enables the formal synthesis of puupehenol, puupehedione, and hongoquercin A. Antifungal evaluation was performed, and this represents the first biological profiles for (+)-yahazunone, (+)-8-O-acetylyahazunone, and (+)-8-O-acetylyahazunol. (+)-Chromazonarol and (+)-yahazunone are promising candidates against Sclerotinia scleotiorum, with EC50 values of 24.1 and 28.7 μM, respectively, demonstrating advantages over the original model (DM) and synthesized heterocyclic mimic (3a) of meroterpenoids. This will favor the establishment of a chemical repertoire in the management of different plant diseases.

Total synthesis of yahazunol, zonarone and isozonarone

Laube, Thorsten,Schr?der, J?rg,Stehle, Ralf,Seifert, Karlheinz

, p. 4299 - 4309 (2007/10/03)

The synthesis of the marine natural products zonarone and isozonarone was achieved via (+)-albicanic acid, a sesquiterpene of the drimane type. Coupling of the appropiate drimane-synthon with lithiated hydroquinone ethers led to sesquiterpene arenes, which were further modified to the target molecules. Stereoselective epoxidation followed by regioselective opening of the oxirane ring yielded yahazunol.

Synthesis and antitumoral activities of marine ent-chromazonarol and related compounds

Barrero, Alejandro F.,Alvarez-Manzaneda, Enrique J.,Herrador, M. Mar,Chahboun, Rachid,Galera

, p. 2325 - 2328 (2007/10/03)

Efficient syntheses of ent-isozonarol (6a), ent-isozonarone (7a) and ent-chromazonarol (8) from (-)-sclareol (12) are described. 6a and 7a show a significative antitumoral activity.
