Calculate Digit Verification of CAS Registry Number 320581-74:
(8*3)+(7*2)+(6*0)+(5*5)+(4*8)+(3*1)+(2*7)+(1*4)=116
116 % 10 = 6
So 320581-74-6 is a valid CAS Registry Number.

Synthesis of tripeptides containing d-Trp substituted at the indole ring, assessment of opioid receptor binding and in vivo central antinociception

De Marco, Rossella,Bedini, Andrea,Spampinato, Santi,Gentilucci, Luca

, p. 6861 - 6866 (2014)

The noncationizable tripeptide Ac-d-Trp-Phe-GlyNH2 was recently proposed as a novel minimal recognition motif for μ-opioid receptor. The introduction of different substituents (methyl, halogens, nitro, etc.) at the indole of d-Trp significantly influenced receptor affinities and resulted in serum stability and in a measurable effect on central antinociception in mice after ip administration.
