Check Digit Verification of cas no
The CAS Registry Mumber 82829-24-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,2 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82829-24:
(7*8)+(6*2)+(5*8)+(4*2)+(3*9)+(2*2)+(1*4)=151
151 % 10 = 1
So 82829-24-1 is a valid CAS Registry Number.

P-H activation of secondary phosphanes on a parent amido diiridium complex

Selected secondary phosphanes (H-PR2; R = Ph, Cy, iPr) smoothly react with a parent amido-bridged diiridium cyclooctadiene complex affording mixed amido/(bis)phosphido dinuclear species. A careful investigation of the reaction profile, carried out by experimental and theoretical tools, revealed that, after an initial amido/phosphido exchange, at low temperatures a second molecule of secondary phosphane adds to the dinuclear system through an oxidative addition process leading to a hydrido amido/bis(phosphido) mixed-valence complex [IrIII/IrI]. These species rearrange above -10 °C into the most stable isomer that arises from a migration of the hydrido moiety to one of the CH fragments of a coordinated cod molecule, a transformation facilitated by the formation of an intermetallic bond. Further heating of these species reductively eliminates ammonia affording bis(phosphido)-metal-metal bonded complexes. The Royal Society of Chemistry.
