886981-41-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 886981-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,9,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 886981-41:
(8*8)+(7*8)+(6*6)+(5*9)+(4*8)+(3*1)+(2*4)+(1*1)=245
245 % 10 = 5
So 886981-41-5 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%).
