Check Digit Verification of cas no

The CAS Registry Mumber 1372649-93-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,6,4 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1372649-93:
(9*1)+(8*3)+(7*7)+(6*2)+(5*6)+(4*4)+(3*9)+(2*9)+(1*3)=188
188 % 10 = 8
So 1372649-93-8 is a valid CAS Registry Number.

Preparation and determination of optical purity of γ-lysine modified peptide nucleic acid analogues

Peptide nucleic acids (PNAs) are DNA analogues in which the nucleic acid backbone is replaced by a pseudopeptide backbone and nucleobases are attached to the backbone by methylene carbonyl linkers. γ-Carbon modification of the PNA structure allows monomers, and subsequently oligomers, with improved properties to be obtained. In this study, we report the convenient synthesis of γ-lysine-modified PNA monomers for pyrimidine bases (thymine and cytosine) with high optical purity (> 99.5%) and direct enantiomer separation of γ-lysine-modified PNA analogs, using chiral HPLC to determine the optical purity.
