Check Digit Verification of cas no

The CAS Registry Mumber 119569-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,5,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 119569-81:
(8*1)+(7*1)+(6*9)+(5*5)+(4*6)+(3*9)+(2*8)+(1*1)=162
162 % 10 = 2
So 119569-81-2 is a valid CAS Registry Number.

Versatile Bulky N,N′,N′-Substituted 1,2-Ethanediamine Ligands and Their Lithium, Aluminium, and Gallium Derivatives

Kretschmer, Robert,Dehmel, Maximilian,Bodensteiner, Michael

supporting information, p. 965 - 970 (2017/02/15)

Sterically demanding N,N′,N′-substituted 1,2-ethanediamine ligands have been prepared from commercially available starting materials by applying a facile one-step procedure. These ligands offer advantages compared to known systems: a suppressed delocalization due to the saturated backbone inhibits a noninnocent behaviour and the low symmetry of the related metal complexes makes them potential candidates for asymmetric catalysis. The ligands are readily transformed into the corresponding lithium derivatives 4, which in turn act as starting materials to access the corresponding aluminium and gallium dichlorides 5 and 6, respectively. In addition, deprotonation by Al(CH3)3gives rise to the related dimethylalane 7. All main-group element compounds have been studied by means of single X-ray crystallography and spectroscopic methods.
