Check Digit Verification of cas no
The CAS Registry Mumber 188790-91-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,9 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 188790-91:
(8*1)+(7*8)+(6*8)+(5*7)+(4*9)+(3*0)+(2*9)+(1*1)=202
202 % 10 = 2
So 188790-91-2 is a valid CAS Registry Number.

Preparative and structural chemistry of chiral 3-(diphenylphosphanyl)pyrrolidines and their palladium(II) complexes
Nagel, Ulrich,Nedden, Hans Guenter
, p. 385 - 397 (2007/10/03)
The preparation of both enantiomers of 3-diphenylphosphanylpyrrolidine (2) and several N-substituted derivatives together with two Pd complexes of this ligand is reported. From L-malic acid and L-hydroxyproline both enantiomers of 3-hydroxypyrrolidine are prepared without any problems due to epimerization. KPPh2 in the presence of LiCl is shown to be the most effective reagent for the synthesis of 2. The reported X-ray structure determinations of PdI2 complexes show a rather rigid bicyclic hetero-norbornane skeleton. The flexibility of the other parts of the molecules is obvious in several polymorphs revealed by this method. This polymorphism is additionally investigated by a 31P-CP-MAS study. From solution 'H-, 13C- and 31P-NMR studies it is concluded that the bicyclic hetero-norbornane skeleton is retained in solution. VCH Verlagsgesellschaft mbH.
