Check Digit Verification of cas no

The CAS Registry Mumber 189160-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,6 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 189160-72:
(8*1)+(7*8)+(6*9)+(5*1)+(4*6)+(3*0)+(2*7)+(1*2)=163
163 % 10 = 3
So 189160-72-3 is a valid CAS Registry Number.

Amino acids bearing nucleobases for the synthesis of novel peptide nucleic acids

Lowe, Gordon,Vilaivan, Tirayut

, p. 539 - 546 (1997)

All of the four nucleobases found in DNA have been incorporated in their protected form into the 4-position of N-tert-butoxycarbonyl-L-proline methyl ester with cis-stereochemistry. An efficient route for the synthesis of N-tert-butoxycarbonyl-trans-4-hydroxy-D-proline methyl ester has been developed from which the enantiomers may be synthesized. In addition an efficient synthesis of N-tert-butoxycarbonyl-N-(2-hydroxyethyl)glycine methyl ester has been achieved and its hydroxy group replaced with protected nucleobases using the Mitsunobu reaction.
