Check Digit Verification of cas no

The CAS Registry Mumber 26693-58-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,6,9 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 26693-58:
(7*2)+(6*6)+(5*6)+(4*9)+(3*3)+(2*5)+(1*8)=143
143 % 10 = 3
So 26693-58-3 is a valid CAS Registry Number.

Synthesis and characterization of trans-2-aminocyclohexanecarboxylic acid oligomers: An unnatural helical secondary structure and implications for β-peptide tertiary structure

Appella, Daniel H.,Christianson, Laurie A.,Karle, Isabella L.,Powell, Douglas R.,Gellman, Samuel H.

, p. 6206 - 6212 (1999)

The preparation, crystal structures, and circular dichroism (CD) spectra of two oligomers of optically active trans-2-aminocyclohexanecarboxylic acid are reported. In the solid state, both the tetramer and the hexamer of this β-amino acid display a helica
