163659-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 163659-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,6,5 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 163659-46:
(8*1)+(7*6)+(6*3)+(5*6)+(4*5)+(3*9)+(2*4)+(1*6)=159
159 % 10 = 9
So 163659-46-9 is a valid CAS Registry Number.

2-Bromoamides as Synthons for Pseudopeptides containing Aminodicarboxy Units
D'Angeli, Ferruccio,Marchetti, Paolo,Salvadori, Severo,Balboni, Gianfranco
, p. 304 - 305 (2007/10/02)
The monoalkylating and enantioselective behaviour of a chiral 2-bromoamide allows the synthesis of pseudopeptides in which a dipeptide component is changed into an aminodicarboxy moiety, with overall retention of configuration.
