Check Digit Verification of cas no

The CAS Registry Mumber 127588-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,8 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127588-57:
(8*1)+(7*2)+(6*7)+(5*5)+(4*8)+(3*8)+(2*5)+(1*7)=162
162 % 10 = 2
So 127588-57-2 is a valid CAS Registry Number.

N2S2 tetradentate ligands for soft cationic species: preparation of new ligands of potential interest in nuclear medicine

Charbonnel-Jobic, Gaelle,Guemas, Jean-Pierre,Adelaere, Bruno,Parrain, Jean-Luc,Quintard, Jean-Paul

, p. 624 - 636 (2007/10/02)

The synthesis of N2S2 tetradentate ligands of the bis-(enaminothioester) type was carried out starting from 3-(methylthio)-3H-1,2-dithiolylium iodides and diamines.The title compounds, which are potential ligands for soft cationic species, can be obtained from 1,3-diaminopropan-2-ol and subsequently modified into the dissymmetrical succinic acid ester of the ligand and N-hydroxysuccinimide.The appendage of such a linking group on the chelating structure should allow further grafting to monoclonal antibodies in view of potential applications in nuclear medicine. 3H-1,2-dithiole-3-thione / 1,3-diaminopropan-2-ol / bis-(enaminothioester) / N2S2 tetradentate ligand / N-hydroxysuccinimidyl ester
