Check Digit Verification of cas no

The CAS Registry Mumber 779358-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,9,3,5 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 779358-53:
(8*7)+(7*7)+(6*9)+(5*3)+(4*5)+(3*8)+(2*5)+(1*3)=231
231 % 10 = 1
So 779358-53-1 is a valid CAS Registry Number.

Conformational studies of 3,4-dideoxy furanoid sugar amino acid containing analogs of the receptor binding inhibitor of vasoactive intestinal peptide

Chakraborty, Tushar K.,Ramakrishna Reddy,Sudhakar,Uday Kumar,Jagadeshwar Reddy,Kiran Kumar,Kunwar, Ajit C.,Mathur, Archna,Sharma, Rajan,Gupta, Neena,Prasad, Sudhanand

, p. 8329 - 8339 (2007/10/03)

Conformational analysis of vasoactive intestinal peptide (VIP) receptor binding inhibitor Leu1-Met2-Tyr3-Pro 4-Thr5-Tyr6-Leu7-Lys8 1 by various NMR techniques and constrained molecular dynamics (MD) simulation studies revealed that the molecule had a turn structure involving its Tyr 3-Pro4-Thr5-Tyr6 moiety with intramolecular hydrogen bond between Tyr6NH→Tyr3CO. In order to mimic the structure of 1, peptidomimetic analogs 2-4 were synthesized using conformationally constrained scaffolds of 3,4-dideoxy furanoid sugar amino acids (2S,5R)-ddSaa1 5 and its enantiomer (2R,5S)-ddSaa2 6. All these analogs displayed well defined three-dimensional structures akin to that found in 1. Peptides 2 and 3, which differed only in the sugar amino acid stereochemistry, show propensity of structures with identical intramolecular hydrogen bonds between ThrNH→MetCO. A similar structure with a hydrogen bond between TyrNH→MetCO was observed in 4. Graphical Abstract.
