1101835-58-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1101835-58-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,1,8,3 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1101835-58:
(9*1)+(8*1)+(7*0)+(6*1)+(5*8)+(4*3)+(3*5)+(2*5)+(1*8)=108
108 % 10 = 8
So 1101835-58-8 is a valid CAS Registry Number.

Dioxime oxalates; new iminyl radical precursors for syntheses of N-heterocycles

Portela-Cubillo, Fernando,Lymer, James,Scanlan, Eoin M.,Scott, Jackie S.,Walton, John C.

scheme or table, p. 11908 - 11916 (2009/04/06)

Symmetrical and unsymmetrical dioxime oxalates were prepared by treatment of oximes with oxalyl chloride. UV photolysis of these precursors was found to be an atom-efficient way of generating iminyl radicals. The process was most efficient for dioxime oxalates having aryl substituents attached to their C{double bond, long}N bonds. The method was useful for EPR spectroscopic study of iminyl and iminoxyl radicals. Photolyses in toluene solution, of dioxime oxalates containing alkenyl acceptor groups, yielded unsaturated iminyl radicals that ring closed to afford 3,4-dihydro-2H-pyrroles in good yields. Dioxime oxalates with biphenyl substituents also released iminyl radicals that ring closed onto the aromatic acceptor groups and, in acetonitrile solution, this approach provided a useful and atom-efficient method of making substituted phenanthridines.
