1542231-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1542231-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,2,2,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1542231-67:
(9*1)+(8*5)+(7*4)+(6*2)+(5*2)+(4*3)+(3*1)+(2*6)+(1*7)=133
133 % 10 = 3
So 1542231-67-3 is a valid CAS Registry Number.

Iron-Catalyzed arylation of heterocycles via directed c-h bond activation
Sirois, John J.,Davis, Riley,Deboef, Brenton
supporting information, p. 868 - 871 (2014/03/21)
The iron-catalyzed arylation of aromatic heterocycles, such as pyridines, thiophenes, and furans, has been achieved. The use of an imine directing group allowed for the ortho functionalization of these heterocycles with complete conversion in 15 min at 0
