Check Digit Verification of cas no
The CAS Registry Mumber 142627-24-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,2 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142627-24:
(8*1)+(7*4)+(6*2)+(5*6)+(4*2)+(3*7)+(2*2)+(1*4)=115
115 % 10 = 5
So 142627-24-5 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 (2002)
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.
