134440-92-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 134440-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 134440-92:
(8*1)+(7*3)+(6*4)+(5*4)+(4*4)+(3*0)+(2*9)+(1*2)=109
109 % 10 = 9
So 134440-92-9 is a valid CAS Registry Number.

Facile and rapid access to linear and truncated microcystin analogues for the implementation of immunoassays

Clave,Ronco,Boutal,Kreich,Volland,Franck,Romieu,Renard

experimental part, p. 676 - 690 (2010/05/02)

A series of simplified microcystin-LR analogues based on Adda [(2S,3S,8S,9S,4E,6E)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldecadienoic acid] or its corresponding aldol precursor linked to a polypeptide moiety have been synthesised and assessed for thei

Enantiospecific synthesis of N-Boc-Adda: a linear approach.

Pearson,Rinehart,Sugano,Costerison

, p. 2901 - 2903 (2007/10/03)

[structure: see text] Synthesis of the unusual amino acid (2S,3S,8S, 9S)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-4,6-decadienoic acid (Adda), a unit of numerous cyanobacterial toxins, is described. Construction of the target molecule was achieved in 1

An asymmetric synthesis of ADDA, and ADDA-glycine dipeptide using the ss-lactam synthon method

Cundy, Darren J.,Donohue, Andrew C.,McCarthy, Tom D.

, p. 559 - 567 (2007/10/03)

The paper describes the synthesis of the W-Boc lactam 4, and demonstrates that it is an important intermediate in the synthesis of dipeptide 5 (X = H, n = 0, R = Me), an analogue of the ADDA-GIu dipeptide 3. In addition we have described a mild method for the preparation of the amino acid salt ADDA-HC1, and provided synthetic methods, and full characterisation for the previously 'elusive' free amino acid ADDA.
