Check Digit Verification of cas no

The CAS Registry Mumber 169957-63-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,9,5 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 169957-63:
(8*1)+(7*6)+(6*9)+(5*9)+(4*5)+(3*7)+(2*6)+(1*3)=205
205 % 10 = 5
So 169957-63-5 is a valid CAS Registry Number.

Dicationic 2-fluorenonylcarbapenems: Potent anti-MRS agents with improved solubility and pharmacokinetic properties

Greenlee, Mark L.,Laub, Joanne B.,Rouen, Gregory P.,DiNinno, Frank,Hammond, Milton L.,Huber, Joann L.,Sundelof, Jon G.,Hammond, Gail G.

, p. 3225 - 3230 (2007/10/03)

The synthesis and biological evaluation of a series of dicationic-substituted 2-fluorenonylcarbapenems is described. This class of compounds showed enhanced water solubility while maintaining potent activity against MRS. Introduction of a 1-β-methyl substituent was found to improve pharmacokinetics.

Practical synthesis of anti-methicillin-resistant Staphylococcus aureus (MRSA) carbapenem L-742,728

Yasuda, Nobuyoshi,Huffman, Mark A.,Ho, Guo-Jie,Xavier, Lyndon C.,Yang, Chunhua,Emerson, Khateeta M.,Tsay, Fuh-Rong,Li, Yulan,Kress, Michael H.,Rieger, Dale L.,Karady, Sandor,Sohar, Paul,Abramson, Newton L.,DeCamp, Ann E.,Mathre, David J.,Douglas, Alan W.,Dolling, Ulf-H.,Grabowski, Edward J. J.,Reider, Paul J.

, p. 5438 - 5446 (2007/10/03)

Anti-MRSA carbapenem, L-742,728, has been prepared in large quantity using the Suzuki-Miyaura cross-coupling as the key reaction. Three approaches have been examined by varying the coupling reaction between carbapenem nucleus A and side chains B, BC, and
