77171-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77171-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,7 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77171-72:
(7*7)+(6*7)+(5*1)+(4*7)+(3*1)+(2*7)+(1*2)=143
143 % 10 = 3
So 77171-72-3 is a valid CAS Registry Number.

Synthesis and Pharmacological Characterization in Vitro of Cyclic Enkephalin Analogues: Effect of Conformational Constraints on Opiate Receptor Selectivity
DiMaio, John,Nguyen, Thi M.-D.,Lemieux, Carole,Schiller, Peter W.
, p. 1432 - 1438 (2007/10/02)
Using a combination of solid-phase and solution methods, we synthesized a series of cyclic 5> enkephalin analogues by substitution of D-α,ω-diamino acids in position 2 of the enkephalin sequence and cyclization of the ω-amino group to the C
