139166-79-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139166-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,6 and 6 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139166-79:
(8*1)+(7*3)+(6*9)+(5*1)+(4*6)+(3*6)+(2*7)+(1*9)=153
153 % 10 = 3
So 139166-79-3 is a valid CAS Registry Number.

Synthesis of a novel ester analog of nucleic acids bearing a serine backbone

Murata, Asako,Wada, Takeshi

, p. 2933 - 2936 (2006)

A novel analog of nucleic acids bearing an optically active serine ester backbone, serine-based nucleobase-linked polyester (SNE), was synthesized. Monomers containing a thymine base were synthesized from l- and d-serines. Furthermore, reaction conditions

Acyclic nucleotide analogues on the basis of phosphonic acids

Efimtseva,Mikhailov,Fomicheva,Meshkov,Rodionov,Khomutov,De Clercq

, p. 12 - 16 (2007/10/03)

The synthesis of novel nucleotide analogues on the basis of ethylphosphonic acids was described. A rigid structural element, an amide, or a double bond, was characteristic of the compounds synthesized. The antiviral and cytotoxic activities of these compo

New approach to solid phase synthesis of polyamide nucleic acids analogues (PNA) and PNA-DNA conjugates

Stetsenko, Dmitry A.,Lubyako, Elena N.,Potapov, Viktor K.,Azhikina, Tatyana L.,Sverdlov, Evgeny D.

, p. 3571 - 3574 (2007/10/03)

New version of sequential DNA and polyamide solid phase synthesis is applied to the preparation of PNA and PNA-DNA conjugates bearing free 3'-end. N-Mmt protected uracil and thymine PNA monomers are obtained in high yields. Novel support derived from TSK
