Check Digit Verification of cas no

The CAS Registry Mumber 158924-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,9,2 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158924-95:
(8*1)+(7*5)+(6*8)+(5*9)+(4*2)+(3*4)+(2*9)+(1*5)=179
179 % 10 = 9
So 158924-95-9 is a valid CAS Registry Number.

Chelating Coordination of Di- and Triallylamines: Syntheses and NMR Studies of Trimethylphosphane Nickel and Cobalt Complexes

Klein, Hans-Friedrich,Helwig, Michael,Braun, Siegmar

, p. 1563 - 1568 (2007/10/02)

16-Electron complexes of zerovalent nickel with diallylamines, NiL and 2CH22 (4), were synthesized by reduction of NiCl2L2 with magnesium in tetrahydrofuran.NiCl(ν3-C3H5)2 (5), a low-yield byproduct, was also obtained in high yield from NiL4 and C3H5Cl.With triallylamine as starting material complexes NiL were generated exhibiting ν6- and ν4-olefin coordination, respectively. 17-electron cobalt(0) compounds Co(PMe3)2 (8, 9: R = CH3, C6H5) were obtained by reaction of Co(cyclo-C5H8)(PMe3)3 with the corresponding diallylamine, while CoR(PMe3)4 (R = CH3, C6H5) reacted with N,N-diallylaniline to give diamagnetic Co3-C3H4)(ν2-C3H5)NC6H5>(PMe3)2, (10).The coordination mode of allylic functions was deduced from IR, ESR and especially 1H- and 13C-NMR spectra including 2D-NMR experiments. - Key Words: Allylamine nickel complexes / Allylamine cobalt complexes / 2D NMR, TOCSY
