172405-18-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172405-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,4,0 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172405-18:
(8*1)+(7*7)+(6*2)+(5*4)+(4*0)+(3*5)+(2*1)+(1*8)=114
114 % 10 = 4
So 172405-18-4 is a valid CAS Registry Number.

Utilization of a combination of weak hydrogen-bonding interactions and phase segregation to yield highly thermosensitive supramolecular polymers

Sivakova, Sona,Bohnsack, David A.,Mackay, Michael E.,Suwanmala, Phiriyatorn,Rowan, Stuart J.

, p. 18202 - 18211 (2007/10/03)

Supramolecular polymerization, i.e., the self-assembly of polymer-like materials through the utilization of the noncovalent bond, is a developing area of research. In this paper, we report the synthesis and investigation of nucleobase-terminated (N6

Substituted N-ethylglycine derivatives for preparing PNA and PNA/DNA hybrids

-

, (2008/06/13)

There are described N-ethylglycine derivatives of the formula I in which PG is a urethane-type or trityl-type amino protective group which is labile to weak acids, X is NH, O or S, Y is CH2, NH or O, and B' are bases customary in nucleotide chemistry, the exocyclic amino or hydroxyl groups of which being protected by suitable, known protective groups, or are base substitute compounds, and their salts with tert-organic bases, as well as a process for their preparation. The N-ethylglycine derivatives of the formula I are used in the preparation of PNA and PNA/DNA hybrids.
