Check Digit Verification of cas no

The CAS Registry Mumber 193538-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,5,3 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 193538-56:
(8*1)+(7*9)+(6*3)+(5*5)+(4*3)+(3*8)+(2*5)+(1*6)=166
166 % 10 = 6
So 193538-56-6 is a valid CAS Registry Number.

Malic acid: A convenient precursor for the synthesis of peptide secondary structure mimetics

Kim, Hwa-Ok,Lum, Chris,Lee, Min S.

, p. 4935 - 4938 (1997)

Syntheses of optically active ether-linked β-lactams and aza-proline analogues via 4-bromo-2-hydroxybutanoic acid esters derived from (S)- or (R)- malic acid are described. From these intermediates peptide secondary structure mimetics can be synthesized.
