136620-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136620-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,2 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136620-83:
(8*1)+(7*3)+(6*6)+(5*6)+(4*2)+(3*0)+(2*8)+(1*3)=122
122 % 10 = 2
So 136620-83-2 is a valid CAS Registry Number.

Native chemical ligation at phenylalanine
Crich, David,Banerjee, Abhisek
, p. 10064 - 10065 (2008/03/12)
Synthesis of erythro-N-Boc-β-mercapto-l-phenylalanine enables native chemical ligation at phenylalanine. In the form of the S-ethyldisulfanyl derivative, the N-Boc amino acid is used to cap a tetrapeptide generated by Fmoc-SPPS. The native chemical ligati
