Check Digit Verification of cas no

The CAS Registry Mumber 5333-74-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,3 and 3 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5333-74:
(6*5)+(5*3)+(4*3)+(3*3)+(2*7)+(1*4)=84
84 % 10 = 4
So 5333-74-4 is a valid CAS Registry Number.

Di-tert-butyl thiopyridazine boratrane complexes of Co, Ni and Cu

Holler, Stefan,Tüchler, Michael,Knaus, Anna M.,Belaj, Ferdinand,M?sch-Zanetti, Nadia C.

, p. 122 - 129 (2017)

The thiopyridazine based scorpionate ligand sodium tris(3,5-di-tert-butyl-6-thioxopyridazin-1(6H)-yl)hydroborate (NaTntBu,tBu) with two tert-butyl substituents in ortho- and para-position of the thio group was synthesized and fully characterized. Corresponding metallaboratrane complexes [M{B(PntBu,tBu)3}Cl] (M = Co, Ni, Cu) as well as [M{B(PnMe,tBu)3}Cl] (M = Co, Ni) were prepared in good yields. All complexes were characterized by spectroscopic means as well as by single crystal X-ray diffraction studies exhibiting short metal boron bonds (between 2.0186(17) ? and 2.069(3) ?) compared to previously reported boratranes. The two tert-butyl groups attached to the heterocycle significantly increases the solubility of NaTntBu,tBuand the derived metal complexes in apolar solvents compared to the system bearing the smaller substituents. The higher steric demand of the tert-butyl versus methyl group enhances the distortion from trigonal bipyramidal towards square pyramidal which effects the electronic situation within the complexes evidenced by the elongated metal chlorine bond trans to boron.

N-heterocyclic bicyclic lactone compounds

-

Page 7, (2010/02/06)

Novel N-heterocyclic bicyclic lactone compounds of formula I and its novel hydroxyamide precursors of formula IV, are synthesized by coupling a hydroxy acid of formula II with an ester of formula III or a pharmaceutically acceptable salt thereof, in the presence of a peptide coupling reagent to produce a hydroxyamide of formula IV, and cyclizing the hydroxyamide of formula IV to produce compounds of formula 1.
