1388183-67-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1388183-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,8,1,8 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1388183-67:
(9*1)+(8*3)+(7*8)+(6*8)+(5*1)+(4*8)+(3*3)+(2*6)+(1*7)=202
202 % 10 = 2
So 1388183-67-2 is a valid CAS Registry Number.

Expedient synthesis of 1-hydroxy-4- and 1-hydroxy-6-nitroindoles
Bujok, Robert,Wrbel, Zbigniew,Wojciechowski, Krzysztof
experimental part, p. 1315 - 1320 (2012/07/13)
Reaction of -chloroalkyl ketones with 1,3-dinitrobenzenes provides 2,4-dinitrobenzyl ketones which when reduced with tin(II) chloride form 6-nitro derivatives of 1-hydroxyindoles. An alternative approach is the condensation of 2,4- and 2,6-dinitrotoluenes
