Check Digit Verification of cas no
The CAS Registry Mumber 19848-68-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,4 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19848-68:
(7*1)+(6*9)+(5*8)+(4*4)+(3*8)+(2*6)+(1*8)=161
161 % 10 = 1
So 19848-68-1 is a valid CAS Registry Number.

Catalytic amination of 2-substituted pyridines with hydrazine derivatives.

[reaction in text] Protected pyridylhydrazine derivatives were prepared in a one-step palladium-catalyzed amination reaction using chelating phosphine ligands. 2-Pyridyl chlorides, bromides, and triflates were effective electrophiles in these reactions. Di-tert-butyl hydrazodiformate was an excellent hydrazine substrate, and the resulting products were deprotected under mild conditions. Catalytic amination provides a direct route to protected bifunctional hydrazinopyridine linkers that are suitable for metal-bioconjugate syntheses.
