102615-56-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 102615-56-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,6,1 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 102615-56:
(8*1)+(7*0)+(6*2)+(5*6)+(4*1)+(3*5)+(2*5)+(1*6)=85
85 % 10 = 5
So 102615-56-5 is a valid CAS Registry Number.

Michael Adducts of (Alkynylcarbene)pentacarbonylchromium Complexes: Formation, Stereochemistry, and Thermal Rearrangement

Duetsch, Michael,Stein, Frank,Lackmann, Rolf,Pohl, Ehmke,Herbst-Irmer, Regine,Meijere, Armin de

, p. 2051 - 2066 (2007/10/02)

β-Donor-substituted α,β-unsaturated chromium carbene complexes (CO)5CrC(OEt)C=CR(XR'n) (X = N, O, S; 3, 9, 11-16, 22-25) have been synthesized by Michael addition of amines, alcohols, and thiols to alkynylcarbene complexes (CO)5CrC(OEt)C=-CR (1).The configurations of the newly formed C-C double bonds have been determined by NOE/NOESY measurements and X-ray crystal structure analysis.These vinylcarbene complexes lose one carbonyl ligand in refluxing tetrahydrofuran to give tetracarbonyl complexes (CO)4CrC(OEt)C=CR(XR'n) (X = N, O, S; 26-28). Key Words: Chromium, alkynylcarbene complexes / Vinylcarbenechromium complexes, β-donor-substituted / Carbene complexes, vinyl chelated
