14297-16-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 14297-16-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,9 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 14297-16:
(7*1)+(6*4)+(5*2)+(4*9)+(3*7)+(2*1)+(1*6)=106
106 % 10 = 6
So 14297-16-6 is a valid CAS Registry Number.

Convenient synthesis of C-terminal di- and tri-peptide amides from N-protected dipeptidoylbenzotriazoles
Celik, Ilhami,Abdel-Fattah, Ashraf A.A.
experimental part, p. 4923 - 4929 (2009/10/09)
N-Protected dipeptidoylbenzotriazoles react with aqueous ammonia to give dipeptide primary amides (77-98%) and with N-unprotected α-amino amides to afford tripeptide primary amides (82-86%).
