15137-12-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 15137-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,3 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 15137-12:
(7*1)+(6*5)+(5*1)+(4*3)+(3*7)+(2*1)+(1*2)=79
79 % 10 = 9
So 15137-12-9 is a valid CAS Registry Number.

Mechanism of Formation of Peroxocarbonates RhOOC(O)O(Cl)(P)3 and Their Reactivity as Oxygen Transfer Agents Mimicking Monooxygenases. the First Evidence of CO2 Insertion into the O-O Bond of Rh(η2-O2) Complexes

, p. 4254 - 4260 (2008/10/09)

Extended labeling experiments have shown that formation of rhodium peroxocarbonate from CO2 and [RhCl(η2-O2(P)3] (P is PEt2Ph or PEtPh2) proceeds through O-O bond cleavage and CO2 insertion. O-transfer to ancillary phosphine ligand to give R3P=O selectively (>85%) involves the Rh-linked O atom of the peroxo group of RhCl(CO4)(P)3.
