Check Digit Verification of cas no
The CAS Registry Mumber 250220-36-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,2,2 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 250220-36:
(8*2)+(7*5)+(6*0)+(5*2)+(4*2)+(3*0)+(2*3)+(1*6)=81
81 % 10 = 1
So 250220-36-1 is a valid CAS Registry Number.

A novel and efficient approach to the synthesis of 2-vinylbenzylamines is reported. This involves obtaining 2-vinylbenzylamine ligands from tetrahydroisoquinoline by alkylation and reduction followed by the Hofmann cleavage. The resultant 2-vinylbenzyl-amines allowed us to obtain new Hoveyda–Grubbs catalysts, which were thoroughly characterised by NMR, ESIMS, and X-ray crystallography. The utility of this chemistry is further demonstrated by the tests of the novel catalysts (up to 10?2 mol %) in different metathesis reactions such as cross metathesis (CM), ring-closing metathesis (RCM) and ring-opening cross metathesis (ROCM).
Method for preparation of a ruthenium indenylidene complex

Paragraph 0070; 0071, (2014/01/17)
The present invention is directed to a method for the preparation of ruthenium catalyst (PCy3)2Cl2Ru(phenylindenylidene) (Umicore catalyst "M1"). The method comprises a one-step reaction reacting the precursor compound (PPh3)2Cl2Ru(3-phenylindenylidene) with PCy3 in a cyclic ether solvent (preferably THF) in concentrations in the range of 0.2 to 0.6 mol catalyst/I while simultaneously precipitating the product from the reaction mixture. A cyclic ether solvate product with high crystallinity and high purity is obtained.
