72674-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72674-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,7 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72674-29:
(7*7)+(6*2)+(5*6)+(4*7)+(3*4)+(2*2)+(1*9)=144
144 % 10 = 4
So 72674-29-4 is a valid CAS Registry Number.

Studies on Metabolites of Macrophoma commelinae. IV. Substrate Specificity in the Biotransformation of 2-Pyrones to Substituted Benzoic Acids

Sakurai, Ikuo,Miyajima, Hisae,Akiyama, Katsuyoshi,Shimizu, Sakae,Yamamoto, Yuzuru

, p. 2003 - 2011 (2007/10/02)

Substrate specificity in the novel biotransformation from 2-pyrone derivatives to substituted benzoic acids by Macrophoma commelinae (IFO 9570) was investigated by means of feeding experiments with various compounds.Among them, 2-pyrone derivatives substituted by an electron-donating group at C-4, by an electron-withdrawing group at C-5 and by an alkyl group at C-6 were converted to the corresponding benzoic acid derivatives in fairly good yields.The C3-unit precursors and intermediates were examined in stationary or shaking culture.Based on the experimental results obtained, a mechanism for this unique reaction is proposed. macrophoma commelinae IFO 9570; fungi; 2-pyrone; substituted benzoic acid; biotransformation; substrate specificity; aromatic ring formation; macrophomic acid

SYNTHESIS OF PYRENOCINE A AND B

Ichihara, Akitami,Murakami, Kazuo,Sakamura, Sadao

, p. 4005 - 4006 (2007/10/02)

From 5-acetyl-4-hydroxy-6-methyl-α-pyrone, two phytotoxins, pyrenocine A and B, were synthesised and erroneous γ-pyrone structure of the starting compound was corrected on the basis of spectroscopic data.
