Check Digit Verification of cas no

The CAS Registry Mumber 20633-06-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,6,3 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20633-06:
(7*2)+(6*0)+(5*6)+(4*3)+(3*3)+(2*0)+(1*6)=71
71 % 10 = 1
So 20633-06-1 is a valid CAS Registry Number.

Exploring the Subtle Effect of Aliphatic Ring Size on Minor Actinide-Extraction Properties and Metal Ion Speciation in Bis-1,2,4-Triazine Ligands

Zaytsev, Andrey V.,Bulmer, Rachel,Kozhevnikov, Valery N.,Sims, Mark,Modolo, Giuseppe,Wilden, Andreas,Waddell, Paul G.,Geist, Andreas,Panak, Petra J.,Wessling, Patrik,Lewis, Frank W.

, p. 428 - 437 (2020)

The synthesis and evaluation of three novel bis-1,2,4-triazine ligands containing five-membered aliphatic rings are reported. Compared to the more hydrophobic ligands 1–3 containing six-membered aliphatic rings, the distribution ratios for relevant f-block metal ions were approximately one order of magnitude lower in each case. Ligand 10 showed an efficient, selective and rapid separation of AmIII and CmIII from nitric acid. The speciation of the ligands with trivalent f-block metal ions was probed using NMR titrations and competition experiments, time-resolved laser fluorescence spectroscopy and X-ray crystallography. While the tetradentate ligands 8 and 10 formed LnIII complexes of the same stoichiometry as their more hydrophobic analogues 2 and 3, significant differences in speciation were observed between the two classes of ligand, with a lower percentage of the extracted 1:2 complexes being formed for ligands 8 and 10. The structures of the solid state 1:1 and 1:2 complexes formed by 8 and 10 with YIII, LuIII and PrIII are very similar to those formed by 2 and 3 with LnIII. Ligand 10 forms CmIII and EuIII 1:2 complexes that are thermodynamically less stable than those formed by ligand 3, suggesting that less hydrophobic ligands form less stable AnIII complexes. Thus, it has been shown for the first time how tuning the cyclic aliphatic part of these ligands leads to subtle changes in their metal ion speciation, complex stability and metal extraction affinity.

Formation of 1,3-Oxaselenoles via Pummerer Reaction in Selenium Dioxide Oxidation of Cyclic 1,2- and 1,3-Diketones, and the Preparation of 1,5,5-Trimethyl-7-selenabicycloheptane-2,3-dione

Laitalainen, Tarja,Simonen, Tapio,Kivekaes, Raikko,Klinga, Martti

, p. 333 - 340 (2007/10/02)

4,5,6,7-Tetrahydro-4',4',6,6-tetramethylspiro-2',4,6'-trione and related 1,3-oxaselenole derivatives, and not the previously reported selenoxides of type (1), are formed in the selenium dioxide oxidation of cyclohexane-1,3-diones.The structural assignments were made on the basis of n.m.r. spectroscopy, and in the case of (5), X-ray analysis was undertaken.Oxidation of 3,3,5,5-tetramethylcyclohexane-1,2-dione with selenium dioxide yielded the bis-selenide (9) and the 1,3-oxaselenole (10) along with the usual oxidation products, whereas the oxidation of 3,5,5-trimethylcyclohexane-1,2-dione gave the title, bridged selenabicyclic compound.

Ring inversion in some fully α-methylated cycloalkane-1,2-diones

Verheidt, Paul L.,Kruk, Cor,Cerfontain, Hans

, p. 85 - 87 (2007/10/02)

Variable-temperature NMR spectra of 3,5,5,5-tetramethylcyclopentane-1,2-dione (1a) and its 6-, 7- and 8-membered homologues (1b-d) showed conformational isomerization for the letter three compounds, the barrier to their ring inversion being 37.5, 38.9 and 62.7 kJ/mol, respectively.
