Check Digit Verification of cas no

The CAS Registry Mumber 284684-50-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,6,8 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 284684-50:
(8*2)+(7*8)+(6*4)+(5*6)+(4*8)+(3*4)+(2*5)+(1*0)=180
180 % 10 = 0
So 284684-50-0 is a valid CAS Registry Number.

The synthesis of C-2,4,6-trialkylphenyl-substituted ethoxy- and aminocarbene tungsten complexes 1a-c (R = Me, iPr and tBu) and 2a,b (R = Me, iPr) and the reaction of 2a,b with [bis(trimethylsilyl)methylene]chlorophosphane (3) in the presence of triethylam

Synthesis and spectroscopic data of para-substituted (3-phenyl-2H-azaphosphirene)tungsten complexes

Streubel, Rainer,Ostrowski, Annette,Priemer, Siegfried,Rohde, Udo,Jeske, Joerg,Jones, Peter G.

, p. 257 - 261 (2007/10/03)

High-yield synthesis of para-substituted pentacarbonyl(3-phenyl-2H-azaphosphirene)tungsten complexes is reported, using a multi-step rearrangement reaction. Spectroscopic and mass-spectrometric data of these heterocyclic complexes are discussed; the 31P-NMR-chemical shifts clearly reflect the electronic influence of the para-phenyl substituents and the correlation with Hammett σp-constants is almost linear.
