Check Digit Verification of cas no
The CAS Registry Mumber 140924-73-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,2 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140924-73:
(8*1)+(7*4)+(6*0)+(5*9)+(4*2)+(3*4)+(2*7)+(1*3)=118
118 % 10 = 8
So 140924-73-8 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
