13604-54-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 13604-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,6,0 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13604-54:
(7*1)+(6*3)+(5*6)+(4*0)+(3*4)+(2*5)+(1*4)=81
81 % 10 = 1
So 13604-54-1 is a valid CAS Registry Number.

New mixed-donor unsymmetrical P-N-P ligands and their palladium(II) complexes

Necas,Foreman,Marek,Woollins,Novosad

, p. 1256 - 1263 (2007/10/03)

Unsymmetrical bidentate ligands R2P(E)-N(H)-P(E′)R′2 [R, R′ = Ph, OPh, iPr; E, E′ = O, S, Se] have been synthesised using the condensation reaction of an amino compound, R2P(E)NH2 [R = PhO, Ph; E = O, S, Se], with a phosphorus electrophile, R′2P(E′)C1 [R′ = iPr, Ph, OPh; E′ = O, S, Se]. Deprotonated ligands (with KOtBu) can be treated with Pd(OAc)2 to give [Ph2P(S)-N-P(O)(OPh)2]2Pd, [iPr2P(S)-N-P(O)(OPh)2]2Pd and [Ph2P(S)-N-P(S)(OPh)2]2Pd, which show either four-membered or six-membered chelate rings. The new compounds were studied spectroscopically (NMR, IR and Raman) and by X-ray crystallography.
