928787-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928787-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,7,8 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 928787-83:
(8*9)+(7*2)+(6*8)+(5*7)+(4*8)+(3*7)+(2*8)+(1*3)=241
241 % 10 = 1
So 928787-83-1 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%).
