121773-10-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121773-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,7 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121773-10:
(8*1)+(7*2)+(6*1)+(5*7)+(4*7)+(3*3)+(2*1)+(1*0)=102
102 % 10 = 2
So 121773-10-2 is a valid CAS Registry Number.

ENZYMATIC FORMATION OF AN ISOPEPTIDE BOND INVOLVING THE ε-AMINO GROUP OF LYSINE
Kitaguchi, Hiroshi,Tai, Dar-Fu,Klibanov, Alexander M.
, p. 5487 - 5488 (1988)
Bacterial protease and lipase act as regioselective preparative catalyst of peptide bond synthesis in anhydrous organic solvents: when a derivative of lysine is used as the amino component, only its ε-NH2 group reacts (to give an isopeptide linkage).
