321837-83-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 321837-83-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,8,3 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 321837-83:
(8*3)+(7*2)+(6*1)+(5*8)+(4*3)+(3*7)+(2*8)+(1*3)=136
136 % 10 = 6
So 321837-83-6 is a valid CAS Registry Number.

Ethylene glycol and amino acid derivatives of 5-aminolevulinic acid as new photosensitizing precursors of Protoporphyrin IX in cells

Berger,Greppi,Siri,Neier,Juillerat-Jeanneret

, p. 4738 - 4746 (2000)

Protoporphyrin IX (PpIX) is used as a photosensitizing agent in photodynamic detection and therapy (PDT) of cancer and is synthesized intracellularly from aminolevulinic acid (ALA) precursors. To evaluate means to specifically target ALA derivatives to de

Improved peptide prodrugs of 5-ALA for PDT: Rationalization of cellular accumulation and protoporphyrin IX production by direct determination of cellular prodrug uptake and prodrug metabolization

Giuntini, Francesca,Bourré, Ludovic,MacRobert, Alexander J.,Wilson, Michael,Eggleston, Ian M.

supporting information; experimental part, p. 4026 - 4037 (2010/01/06)

Twenty-seven dipeptide derivatives of general structure Ac-Xaa-ALA-OR were synthesized as potential prodrugs for 5-aminolaevulinic acid-based photodynamic therapy (ALA-PDT). Xaa is an R-amino acid, chosen to provide a prodrug with appropriately tailored l
