Check Digit Verification of cas no

The CAS Registry Mumber 116934-84-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,9,3 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 116934-84:
(8*1)+(7*1)+(6*6)+(5*9)+(4*3)+(3*4)+(2*8)+(1*4)=140
140 % 10 = 0
So 116934-84-0 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

, 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
