1314778-12-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1314778-12-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,7,7 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1314778-12:
(9*1)+(8*3)+(7*1)+(6*4)+(5*7)+(4*7)+(3*8)+(2*1)+(1*2)=155
155 % 10 = 5
So 1314778-12-5 is a valid CAS Registry Number.

Fmoc synthesis of peptide thioesters without post-chain-assembly manipulation
Zheng, Ji-Shen,Chang, Hao-Nan,Wang, Feng-Liang,Liu, Lei
, p. 11080 - 11083 (2011/09/15)
An operationally simple method for the synthesis of peptide thioesters is developed using standard Fmoc solid-phase peptide synthesis procedures. The method relies on the use of a premade enamide-containing amino acid which, in the final TFA cleavage step
