121007-17-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121007-17-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,0 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121007-17:
(8*1)+(7*2)+(6*1)+(5*0)+(4*0)+(3*7)+(2*1)+(1*7)=58
58 % 10 = 8
So 121007-17-8 is a valid CAS Registry Number.

Synthesis and structure - Phytotoxicity relationships of acetylenic phenols and chromene metabolites, and their analogues, from the grapevine pathogen Eutypa lata

Smith, Leverett R.,Mahoney, Noreen,Molyneux, Russell J.

, p. 169 - 176 (2007/10/03)

Eutypa lata, the fungus responsible for dying-arm disease in grapevines, produces a number of structurally related secondary metabolites, of which eutypine (1) has been implicated as the principal phytotoxin. However, analysis of an E. lata strain from California known to be pathogenic to grapevines showed that eutypine was not present, suggesting that other metabolites could be phytotoxic. Investigation of the relative phytotoxicities of individual metabolites has been limited by insufficient material and lack of a reliable bioassay. Metabolites of particular interest and their precursors were therefore synthesized, and a rapid, quantitative bioassay via topical application of individual compounds to disks of grape leaves and measurement of chlorophyll loss was developed to provide a relative measure of tissue damage. The recently reported metabolite eulatachromene (2) was found to have phytotoxicity greater than that of eutypine (1). The cyclization product, 5-formyl-2-methylvinyl[1]benzofuran (3), also showed significant activity, whereas the reduction product, eutypinol (4), was inactive, as was the quinol, siccayne (5). These results indicate that before strains of Eutypa are incriminated as pathogenic they must be analyzed for the presence or absence of specific constituents for which the phytotoxicity has been unequivocally established.
