144527-39-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144527-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,5,2 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144527-39:
(8*1)+(7*4)+(6*4)+(5*5)+(4*2)+(3*7)+(2*3)+(1*9)=129
129 % 10 = 9
So 144527-39-9 is a valid CAS Registry Number.

Synthesis of 2,2-disubstituted pyrrolidine-4-carboxylic acid derivatives and their incorporation into β-peptide oligomers

Huck, Bayard R.,Gellman, Samuel H.

, p. 3353 - 3362 (2007/10/03)

(Chemical Equation Presented) We have recently shown that members of a new class of β-peptides, containing 2,2-disubstituted pyrrolidine-4-carboxylic acid residues, display discrete conformational preferences despite the impossibility of internal hydrogen bonding (Huck et al. J. Am. Chem. Soc. 2003, 125, 9035). Here we describe the synthesis of a variety of 2,2-disubstituted pyrrolidine-4-carboxylic derivatives that bear a diverse set of side chains and protecting groups suitable for oligomer synthesis. In addition, we discuss coupling methods for construction of oligomers in solution and on solid phase. Non-hydrogen bonded foldamers such as those generated from 2,2-disubstituted pyrrolidine-4-carboxylic acids may be useful in biomedical applications because the low intrinsic polarity of their backbones may promote bioavailability.
