Calculate Digit Verification of CAS Registry Number 142802-58:
(8*1)+(7*4)+(6*2)+(5*8)+(4*0)+(3*2)+(2*5)+(1*8)=112
112 % 10 = 2
So 142802-58-2 is a valid CAS Registry Number.

Multiple Bonds Between Main-Group Elements and Transition Metals, CXX. - Niobium and Tantalum Amide Complexes and New Cyclocarbodisilazanes

Herrmann, Wolfgang A.,Dyckhoff, Florian,Herdtweck, Eberhardt

, p. 2651 - 2656 (2007/10/02)

The new niobium- and tantalum complexes 3a and 3b of formula (M = Nb, a; Ta, b) are accessible by the reaction of the oxychlorides MOCl3 with the lithium amide (2) in 30 and 19percent isolated yield, resp.The new silazanes cyclo2 (5) and cyclo-3 (6) are prepared from (CH3)2ClSiCH2CH2SiCl(CH3)2 and NH3.Their structures - ten- and fifteeen-membered rings - were determined by single-crystal structure analyses. Key Words: Niobium complexes / Tantalum complexes / Silylamides / Cyclocarbodisilazanes
