168559-03-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168559-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,5,5 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 168559-03:
(8*1)+(7*6)+(6*8)+(5*5)+(4*5)+(3*9)+(2*0)+(1*3)=173
173 % 10 = 3
So 168559-03-3 is a valid CAS Registry Number.

Alkyne-niobium(I) complexes with functionalized alkynes: synthesis, structure and reactivity
Rodewald, Dieter,Schulzke, Carola,Rehder, Dieter
, p. 29 - 36 (2007/10/03)
The reaction between INb(CO)3(PR3)3 and diynes yielded the complexes all-trans- (PR3 = PEt3; diyne = 2,4-hexadiyne (1a), 1,5-hexadiyne (1b).PR3 = PMe2Ph, diyne = 2,6-octadiyne (1c)).Only one of the acetylenic bonds coordinates.Reactio
