Check Digit Verification of cas no

The CAS Registry Mumber 181118-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,1,1 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 181118-08:
(8*1)+(7*8)+(6*1)+(5*1)+(4*1)+(3*8)+(2*0)+(1*8)=111
111 % 10 = 1
So 181118-08-1 is a valid CAS Registry Number.

D-amino acid specific proteases and native all-L-proteins: A convenient combination for semisynthesis

Wehofsky, Nicole,Pech, Andreas,Liebscher, Sandra,Schmidt, Stephanie,Komeda, Hidenobu,Asano, Yasuhisa,Bordusa, Frank

supporting information; experimental part, p. 5456 - 5460 (2009/03/12)

(Figure Presented) Side reactions side-stepped: A D-amino acid specific protease was used for the first time in the chemoenzymatic synthesis of a native protein, the peptidyl prolyl cis/trans isomerase parvulin 10 from E. coli (see scheme). Side reactions that complicate synthesis with L-amino acid specific enzymes are avoided in this approach.
