The CAS Registry Mumber 159801-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,8,0 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 159801-09:
(8*1)+(7*5)+(6*9)+(5*8)+(4*0)+(3*1)+(2*0)+(1*9)=149
149 % 10 = 9
So 159801-09-9 is a valid CAS Registry Number.

Enantiospecific and Diastereoselective Synthesis of cis Monobactams through Electrophilic Amination of Chiral 3-Hydroxyesters

Banfi, Luca,Cascio, Giuseppe,Guanti, Giuseppe,Manghisi, Elso,Narisano, Enrica,Riva, Renata

, p. 11967 - 11982 (1994)

A new efficient entry into cis monobactams starting from β-hydroxyesters is reported.This preparation is based on the stereoselective "electrophilic amination" of β-hydroxyester dianions and on Miller's biomimetic synthesis of the β-lactam nucleus.By this route, key intermediates for the preparation of pharmacologically important cis aztreonam 2 and carumonam 3 were prepared.
