131088-90-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131088-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,0,8 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131088-90:
(8*1)+(7*3)+(6*1)+(5*0)+(4*8)+(3*8)+(2*9)+(1*0)=109
109 % 10 = 9
So 131088-90-9 is a valid CAS Registry Number.

Paragraph 0084; 0086-0087, (2021/06/13)

The invention relates to a method for preparing a deuterated compound through decarboxylation and deuteration of carboxylic acid. According to the method, a carboxylic acid compound is used as a raw material, hydrogen atoms of carboxylate radicals are exc

Side Chain Hydroxylation of Aromatic Compounds by Fungi. Part 4. Influence of the para Substituent on Kinetic Isotope Effects During Benzylic Hydroxylation by Mortierella isabellina

Holland, Herbert L.,Brown, Frances M.,Conn, Morgan

, p. 1651 - 1655 (2007/10/02)

The benzylic hydroxylation of a series of para-substituted toluenes by the fungus Mortierella isabellina has been studied by using CD3, CHD2, and CH2D methyl labelled substrates.Inter- and intramolecular primary and secondary deuterium kinetic isotope effect ratios have been determined: the intermolecular primary effects are maximal with strongly electron-withdrawing para substituents (R = CN and CF3), while the intramolecular primary effects are minimal for R = H but increase in instances where R is electron donating or withdrawing.These results are interpreted in terms of a dependence of the hydroxylation mechanism on the nature of the para substituent.
