Check Digit Verification of cas no

The CAS Registry Mumber 1043922-58-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,3,9,2 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1043922-58:
(9*1)+(8*0)+(7*4)+(6*3)+(5*9)+(4*2)+(3*2)+(2*5)+(1*8)=132
132 % 10 = 2
So 1043922-58-2 is a valid CAS Registry Number.

Azadipeptide nitriles: Highly potent and proteolytically stable inhibitors of papain-like cysteine proteases

Loeser, Reik,Frizler, Maxim,Schilling, Klaus,Guetschow, Michael

supporting information; experimental part, p. 4331 - 4334 (2009/02/08)

(Chemical Presented) Nitrogen instead of carbon: Azadipeptide nitriles resulting from CH/N exchange in the P1 position (see picture) are hitherto unknown. To access these compounds by conversion of amino acid-derived hydrazides with cyanogen bromide both nitrogen atoms of the hydrazide must be substituted. Despite a methylated P2-P1 peptide bond, the azadipeptide nitriles show a strong inhibitory activity against cysteine proteases, and a high stability towards chymotryptic hydrolysis.
