193959-26-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 193959-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,5 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 193959-26:
(8*1)+(7*9)+(6*3)+(5*9)+(4*5)+(3*9)+(2*2)+(1*6)=191
191 % 10 = 1
So 193959-26-1 is a valid CAS Registry Number.

Efficient and highly stereoselective synthesis of a β-lactam inhibitor of the serine protease prostate-specific antigen

Annunziata, Rita,Benaglia, Maurizio,Cinquini, Mauro,Cozzi, Franco,Puglisi, Alessandra

, p. 1813 - 1818 (2007/10/03)

An efficient synthesis of a β-lactam precursor of the serine protease, prostate-specific antigen inhibitor 1 has been accomplished. The synthesis relies on two completely stereoselective reactions that allow the introduction of the stereocenters at C-3 an

Design and synthesis of novel monocyclic β-lactam inhibitors of prostate specific antigen

Adlington, Robert M.,Baldwin, Jack E.,Chen, Beining,Cooper, Stephen L.,McCoull, William,Pritchard, Gareth J.,Howe, Trevor J.,Becker, Gerald W.,Hermann, Robert B.,McNulty, Ann M.,Neubauer, Blake L.

, p. 1689 - 1694 (2007/10/03)

A novel series of monocyclic β-lactam analogues was designed using a homology derived model of prostate specific antigen (PSA) and by application of a multiple copy simultaneous search technique. Syntheses were conducted by assembly of the β-lactam core v
