Check Digit Verification of cas no
The CAS Registry Mumber 87694-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,9 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87694-58:
(7*8)+(6*7)+(5*6)+(4*9)+(3*4)+(2*5)+(1*8)=194
194 % 10 = 4
So 87694-58-4 is a valid CAS Registry Number.

Synthesis, characterization and in vitro hydrolysis of L-pyroglutamyl-L-tryptophan derivatives as potential drug carriers
Bousquet,De Regis,Giannola,Santagati,Tirendi
, p. 260 - 262 (2007/10/02)
The condensation reaction of L-tryptophan with L-pyroglutamic acid or its N-carbobenzyloxy derivative in the presence of dicyclohexylcarbodiimide (DCC) afforded dipeptide molecules identified as L-pyroglutamyl-L-tryptophan derivatives. The synthesized dipeptide molecules offer a potentially useful means to obtain drug carriers and improve the poor uptake of drug molecules to the brain. The chemical hydrolysis characteristics in simulated gastro-intestinal juices are reported. No significant hydrolysis was observed.
