Check Digit Verification of cas no

The CAS Registry Mumber 1219804-18-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,8,0 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1219804-18:
(9*1)+(8*2)+(7*1)+(6*9)+(5*8)+(4*0)+(3*4)+(2*1)+(1*8)=148
148 % 10 = 8
So 1219804-18-8 is a valid CAS Registry Number.

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.
