528891-45-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 528891-45-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,8,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 528891-45:
(8*5)+(7*2)+(6*8)+(5*8)+(4*9)+(3*1)+(2*4)+(1*5)=194
194 % 10 = 4
So 528891-45-4 is a valid CAS Registry Number.

Synthesis of small cyclic peptides via intramolecular Heck reactions
Reddy, P. Rajamohan,Balraju,Madhavan,Banerji, Biswadip,Iqbal, Javed
, p. 353 - 356 (2003)
Tripeptides having a 3-bromobenzyl group at the C-termini and an acryloyl group at the N termini undergo efficient intramolecular Heck reactions to afford the corresponding cyclic peptides in good yields. Synthesis of two such peptides is discussed.
