Check Digit Verification of cas no

The CAS Registry Mumber 399559-57-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,9,5,5 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 399559-57:
(8*3)+(7*9)+(6*9)+(5*5)+(4*5)+(3*9)+(2*5)+(1*7)=230
230 % 10 = 0
So 399559-57-0 is a valid CAS Registry Number.

Barbier-type diastereoselective allylation of α-amino aldehydes with an enantiopure 2-sulfinylallyl building block

Marquez, Francesc,Montoro, Raul,Llebaria, Amadeu,Lago, Elena,Molins, Elies,Delgado, Antonio

, p. 308 - 311 (2002)

An optimized procedure for the diastereoselective allylation under aqueous Barbier conditions of a series of α-amino aldehydes with our new chiral building block (Ss)-3-chloro-2-(p-tolylsulfinyl)-1-propene [(Ss)-1a] to afford enantiomerically pure sulfinylamino alcohols in good yields and diastereoselectivites is reported. High levels of diastereoinduction can be achieved from α-amino aldehydes configurationally related to natural α-amino acids.
