Check Digit Verification of cas no

The CAS Registry Mumber 14107-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,1,0 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14107-99:
(7*1)+(6*4)+(5*1)+(4*0)+(3*7)+(2*9)+(1*9)=84
84 % 10 = 4
So 14107-99-4 is a valid CAS Registry Number.

Volatiles from the fungal microbiome of the marine sponge: Callyspongia cf. flammea

Barra, Lena,Barac, Paul,K?nig, Gabriele M.,Crüsemann, Max,Dickschat, Jeroen S.

, p. 7411 - 7421 (2017)

The volatiles emitted by five fungal strains previously isolated from the marine sponge Callyspongia cf. flammea were captured with a closed-loop stripping apparatus (CLSA) and analyzed by GC-MS. Besides several widespread compounds, a series of metabolites with interesting bioactivities were found, including the quorum sensing inhibitor protoanemonin, the fungal phytotoxin 3,4-dimethylpentan-4-olide, and the insect attractant 1,2,4-trimethoxybenzene. In addition, the aromatic polyketides isotorquatone and chartabomone that are both known from Eucalyptus and a new O-desmethyl derivative were identified. The biosynthesis of isotorquatone was studied by feeding experiments with isotopically labeled precursors and its absolute configuration was determined by enantioselective synthesis of a reference compound. Bioactivity testings showed algicidal activity for some of the identified compounds, suggesting a potential ecological function in sponge defence.
