Check Digit Verification of cas no

The CAS Registry Mumber 76264-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,2,6 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76264-40:
(7*7)+(6*6)+(5*2)+(4*6)+(3*4)+(2*4)+(1*0)=139
139 % 10 = 9
So 76264-40-9 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.
