21055-93-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21055-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,5 and 5 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21055-93:
(7*2)+(6*1)+(5*0)+(4*5)+(3*5)+(2*9)+(1*3)=76
76 % 10 = 6
So 21055-93-6 is a valid CAS Registry Number.

The preparation and structural characterisation of bis(N,N-diethyl-monothiocarbamato)complexes of cadmium and of the novel tetrameric complex [Et4Zn4(OSCNEt2)2(NEt 2)2]: Two new bonding modes for the monothiocarbamato ligand

Chunggaze, Mohammed,Malik, M. Azad,O'Brien, Paul,White, Andrew J. P.,Williams, David J.

, p. 3839 - 3844 (1998)

Bis(diethylmonothiocarbamato) complexes of cadmium (1) and zinc (2) were prepared by the reaction of sodium monothiocarbamate with cadmium acetate or zinc chloride. Compound 1 crystallises as clear needles and a single crystal X-ray analysis showed it to be monoclinic (space group C2/c, no. 15), a = 22.143(2), b = 9.239(2), c = 7.553(3) A, β = 101.41(2)° and Z = 4. The coordination at the cadmium centre is distorted trigonal prismatic with two S,O-bidentate and two O-monodentate diethylmonothiocarbamato ligands. This new, O-binucleating, bonding mode for the monothiocarbamato ligand results in polymeric chains which are co-aligned to give a distorted close-packed hexagonal array. The cage complex [Et4Zn4(OSCNEt2)2(NEt 2)2] 3 is formed as the only isolable product from the reaction of EtZnNEt2 with carbonyl sulfide. Clear rhombic crystals (space group P21/n, no. 14) were formed [a = 10.818(1), b = 14.732(1), c = 11.758(2) A, β = 103.25(1)° and Z = 2]. The cage is comprised of two six-membered Zn2CNOS metallocycles that are linked by pairs of Zn-S and Zn-O bonds. In 3 a second new bonding mode for the monothiocarbamato ligand is observed in which both the oxygen and sulfur atoms are binucleating. Molecules of 3 pack to form a slightly distorted cubic close-packed array. The variable temperature 1H NMR of 3 is also reported and shows the cluster to remain intact in solution.
