501435-94-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 501435-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,4,3 and 5 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 501435-94:
(8*5)+(7*0)+(6*1)+(5*4)+(4*3)+(3*5)+(2*9)+(1*4)=115
115 % 10 = 5
So 501435-94-5 is a valid CAS Registry Number.

Versatile synthesis of 3,5-disubstituted 2-fluoropyridines and 2-pyridones
Sutherland, Andrew,Gallagher, Timothy
, p. 3352 - 3355 (2007/10/03)
5-Bromo-2-fluoro-3-pyridylboronic acid (3) was prepared in high yield by ortho-lithiation of 5-bromo-2-fluoropyridine (1), followed by reaction with trimethylborate. Suzuki reaction of 3 with a range of aryl iodides gave 3-monosubstituted 5-bromo-2-fluoro
