127966-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127966-37-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,6 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127966-37:
(8*1)+(7*2)+(6*7)+(5*9)+(4*6)+(3*6)+(2*3)+(1*7)=164
164 % 10 = 4
So 127966-37-4 is a valid CAS Registry Number.

Cyclopalladated ethylenediamine complexes on the basis of 4-phenylpyrimidine and 4,6-diphenylpyrimidine

Ivanova,Puzyk,Balashev

, p. 1236 - 1240 (2008/12/22)

Mono-and binuclear cyclopalladated complexes [Pd(ppm)En]ClO4, [Pd(Hdphpm)En]ClO4, and [(PdEn)2(μ-dphpm)]ClO 4 (ppm- is the deprotonated form of 4-phenylpyridine, Hdphpm- and dphpm2- are the mono-and bisdeprotonated forms of 4,6-diphenylpyrimidine, En is 1,2-diaminoethane) were prepared and characterized by means of 1H NMR and electronic absorption and emission spectroscopy, and cyclic voltammetry. It was shown that cyclopalladation leads to a bathochromic shift of intraligand absorption and phosphorescence bands, appearance of new absorption band associated with metal-to-ligand charge transfer, and an anodic potential shift of the ligand-centered electroreduction Hppm ≈ H2dphpm + ≈ [Pd(Hdphpm)En]+ 2(μ-dphpm)]2+.
