69861-90-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69861-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,6 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69861-90:
(7*6)+(6*9)+(5*8)+(4*6)+(3*1)+(2*9)+(1*0)=181
181 % 10 = 1
So 69861-90-1 is a valid CAS Registry Number.

Reverse proteolysis promoted by in situ generated peptide ester fragments
Wehofsky, Nicole,Koglin, Norman,Thust, Sven,Bordusa, Frank
, p. 6126 - 6133 (2007/10/03)
In this contribution we describe a general synthesis concept for the in situ preparation of protease specific reactants using methyl thioesters as universal precursors. The precursor esters are readily available by standard synthesis procedures and can be
