Check Digit Verification of cas no

The CAS Registry Mumber 253159-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,1,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 253159-20:
(8*2)+(7*5)+(6*3)+(5*1)+(4*5)+(3*9)+(2*2)+(1*0)=125
125 % 10 = 5
So 253159-20-5 is a valid CAS Registry Number.

Expanding the scope of PNA-encoded libraries: divergent synthesis of libraries targeting cysteine, serine and metallo-proteases as well as tyrosine phosphatases

Debaene, Fran?ois,Da Silva, Julien A.,Pianowski, Zbigniew,Duran, Fernando J.,Winssinger, Nicolas

, p. 6577 - 6586 (2007)

Seven PNA-encoded combinatorial libraries targeting proteases and phosphatases with covalent reversible and irreversible mechanism-based inhibitors were prepared. The libraries were synthesized using modified PNA monomers, which dramatically increase the water solubility of the libraries in biologically relevant buffers. The libraries were shown to selectively inhibit targeted enzymes.
