Check Digit Verification of cas no

The CAS Registry Mumber 193693-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,6,9 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 193693-68:
(8*1)+(7*9)+(6*3)+(5*6)+(4*9)+(3*3)+(2*6)+(1*8)=184
184 % 10 = 4
So 193693-68-4 is a valid CAS Registry Number.

Preparation of β2-amino acid derivatives (β2hThr, β2hTrp, β2hMet, β2hPro, β2hLys, pyrrolidine-3-carboxylic acid) by using DIOZ as chiral auxiliary

Gessier, Francois,Schaeffer, Laurent,Kimmerlin, Thierry,Floegel, Oliver,Seebach, Dieter

, p. 2235 - 2249 (2007/10/03)

The title compounds were prepared from valine-derived N-acylated oxazolidin-2-ones, 1-3, 7, 9, by highly diastereoselective (≥ 90%) Mannich reaction (→ 4-6; Scheme 1) or aldol addition (→ 8 and 10; Scheme 2) of the corresponding Ti- or B-enolates as the key step. The superiority of the '5,5-diphenyl-4-isopropyl-1,3-oxazolidin-2-one' (DIOZ) was demonstrated, once more, in these reactions and in subsequent transformations leading to various t-Bu-, Boc-, Fmoc-, and Cbz-protected β2-homoamino acid derivatives 11-23 (Schemes 3-6). The use of ω-bromo-acyl-oxazolidinones 1-3 as starting materials turned out to open access to a variety of enantiomerically pure trifunctional and cyclic carboxylic-acid derivatives.
