Check Digit Verification of cas no

The CAS Registry Mumber 262299-32-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,2,2,9 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 262299-32:
(8*2)+(7*6)+(6*2)+(5*2)+(4*9)+(3*9)+(2*3)+(1*2)=151
151 % 10 = 1
So 262299-32-1 is a valid CAS Registry Number.

Synthesis and structure-activity relationship study of the new set of trypsin-like proteinase inhibitors

Zlatoidsky, Pavol,Maliar, Tibor

, p. 1023 - 1034 (2007/10/03)

A new set of 25 trypsin-like proteinase inhibitors was prepared and the inhibiting activity on trypsin, thrombin, plasmin and urokinase was measured. The structure-activity relationship is discussed. High inhibiting activities were observed in 4-guanidinobenzoic acid esters only. The replacement of this moiety for N-formamidinyl-isonipecotic acid or an arginine moiety caused almost total loss of the activity. In the series of 4-guanidinobenzoic acid esters, any important influence of the ester-groups reactivity was observed. The trypsin-thrombin selectivity in the compounds with the guanidine-remote carboxylic function was also observed.
