121773-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121773-11-3 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 1 respectively.
Calculate Digit Verification of CAS Registry Number 121773-11:
(8*1)+(7*2)+(6*1)+(5*7)+(4*7)+(3*3)+(2*1)+(1*1)=103
103 % 10 = 3
So 121773-11-3 is a valid CAS Registry Number.

Regioselective modification of Lysine's amino groups by proteases.
Kitaguchi,Ono,Itoh,Klibanov
, p. 3067 - 3073 (2007/10/02)
The regioselectivity of six serine proteases for the amino groups of lysine was investigated. alpha-Chymotrypsin showed a preference for the alpha-amino group, although the selectivity can be varied 10-fold depending on the reaction medium. Subtilisin Car
