The CAS Registry Mumber 475147-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,1,4 and 7 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 475147-00:
(8*4)+(7*7)+(6*5)+(5*1)+(4*4)+(3*7)+(2*0)+(1*0)=153
153 % 10 = 3
So 475147-00-3 is a valid CAS Registry Number.

Preparation of 2-arylated-1,4-phenylenediamines by palladium-catalyzed cross-coupling reactions

Jensen, Anne Eeg,Knochel, Paul

, p. 122 - 128 (2007/10/03)

Protected 2-iodol-1,4-phenylenediamines were converted to the corresponding magnesium derivative by performing an iodine-magnesium exchange. After transmetalation with zinc bromide, a palladium(0)-catalyzed cross-coupling with various aryl iodides and 5-bromo-2-carbethoxyfuran furnished the expected cross-coupling products in 52-79% yield.
