Check Digit Verification of cas no
The CAS Registry Mumber 56559-60-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,5 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 56559-60:
(7*5)+(6*6)+(5*5)+(4*5)+(3*9)+(2*6)+(1*0)=155
155 % 10 = 5
So 56559-60-5 is a valid CAS Registry Number.

Pd-catalyzed cascade reactions between: O -iodo- N -alkenylanilines and tosylhydrazones: Novel approaches to the synthesis of polysubstituted indoles and 1,4-dihydroquinolines
Paraja, Miguel,Valdés, Carlos

Two different Pd-catalyzed cascade reactions between o-iodo-N-alkenylanilines and tosylhydrazones are described. The outcome of the cascade processes is determined by the substitution on the N-alkenyl fragment. The reactions with N-tosyl-N-ethylene-o-iodoanilines lead to indoles through a sequence that involves the sequential migratory insertions of a carbene ligand and a C-C double bond, featuring a 5-exo-trig cyclization. The reactions with N-alkyl-N-alkenyl-o-iodoanilines provide 1,4-dihydroquinolines through a cascade reaction that includes a formal 6-endo-trig cyclization. In both cases the benzofused heterocycles are built through the formation of two C-C bonds on the hydrazonic carbon atom.
