Check Digit Verification of cas no

The CAS Registry Mumber 160998-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,9,9 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 160998-89:
(8*1)+(7*6)+(6*0)+(5*9)+(4*9)+(3*8)+(2*8)+(1*9)=180
180 % 10 = 0
So 160998-89-0 is a valid CAS Registry Number.

Addition of dilithiated methyl-3-aminobutanoate to aldehydes proceeds with ul-1,2-induction

Ettmayer, Peter,Huebner, Michael,Gstach, Hubert

, p. 3901 - 3904 (2007/10/02)

Syntheses of 2-substituted 1-hydroxyethylene building blocks, useful as the central moiety of HIV-1 protease inhibitors, is described. Dilithiated N-protected-3-amino-4-phenylbutanoic methyl esters are reacted with aldehydes to give predominantly aldol products with l,u configuration. The diastereomeric ratio depends on the N-protecting group and on the experimental conditions. The configurations are assigned by 1H-NMR of cyclic derivatives and are supported by X-ray structure.
