Check Digit Verification of cas no

The CAS Registry Mumber 127290-82-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,9 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127290-82:
(8*1)+(7*2)+(6*7)+(5*2)+(4*9)+(3*0)+(2*8)+(1*2)=128
128 % 10 = 8
So 127290-82-8 is a valid CAS Registry Number.

Peptide coupling of unprotected amino acids through in situ p-nitrophenyl ester formation

Gagnon, Paul,Huang, Xicai,Therrien, Eric,Keillor, Jeffrey W.

, p. 7717 - 7719 (2007/10/03)

Several series of dipeptides and tripeptides were prepared via an activation-coupling method involving the in situ formation of a p-nitrophenyl ester of an (N-protected) amino acid, followed by coupling with an unprotected amino acid in partially aqueous solutions. The resulting peptide is easily isolated by precipitation. In general, the yields obtained are good to excellent and racemization is minimal. This method is particularly advantageous with respect to its simplicity and lack of obligatory side chain protection/deprotection steps.
