1432270-27-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1432270-27-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,2,2,7 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1432270-27:
(9*1)+(8*4)+(7*3)+(6*2)+(5*2)+(4*7)+(3*0)+(2*2)+(1*7)=123
123 % 10 = 3
So 1432270-27-3 is a valid CAS Registry Number.

Synthesis of murrayaquinone A and analogues via ring-closing C-H arylation
Bedford, Robin B.,Bowen, John G.,Weeks, Amanda L.
, p. 4389 - 4394 (2013/06/26)
A compact synthesis of Murrayaquinone A is reported, based on sequential Buchwald-Hartwig amination/annulative C-H activation followed by oxidation of the intermediate carbazole. The methodology can be readily extended to other analogues with electron-rich quinone rings.
