127399-65-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127399-65-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,3,9 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 127399-65:
(8*1)+(7*2)+(6*7)+(5*3)+(4*9)+(3*9)+(2*6)+(1*5)=159
159 % 10 = 9
So 127399-65-9 is a valid CAS Registry Number.

Monomethyl Ether Derivatives of 7,8-Dihydroxy- and 8,9-Dihydroxy-4-n-propyl-1,2,3,4,4a,5,6,10b-octahydrobenzoquinolines as Possible Products of Metabolism by Catechol-O-methyltransferase

Cannon, Joseph G.,Walker, Kathleen A.,Montanari, Antonio,Long, John Paul,Flynn, Jan R.

, p. 2000 - 2006 (1990)

In order to facilitate identification of possible metabolites arising from in vitro action of catechol-O-methyltransferase upon 7,8-dihydroxy- and 8,9-dihydroxy-4-n-propyl-1,2,3,4,4a,5,6,10b-octahydrobenzoquinolines (11, 12), all four possible monomethyl ether derivatives have been synthesized.Incubation of 11 and 12 with the enzyme revealed that the 8,9-dihydroxy positional isomer 12 (which contains the dopamine moiety held in the β conformation) but not the 7,8-dihydroxy isomer 11 (which holds the dopamine moiety in the α conformation) was a substrate for theenzyme.The sole detectable product of 12 was 8-hydroxy-9-methoxy derivative 15 in which the "meta" hydroxy group of the dopamine moiety is etherified.
