212970-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 212970-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,9,7 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 212970-65:
(8*2)+(7*1)+(6*2)+(5*9)+(4*7)+(3*0)+(2*6)+(1*5)=125
125 % 10 = 5
So 212970-65-5 is a valid CAS Registry Number.

Synthesis of conformationally locked C-nucleosides having a 2,5- dioxabicyclo [2.2.1] heptane ring system

Obika, Satoshi,Hari, Yoshiyuki,Morio, Ken-Ichiro,Imanishi, Takeshi

, p. 215 - 219 (2000)

Some novel C-nucleosides having a 2,5-dioxabicyclo[2.2.1]heptane ring system were successfully synthesized via the coupling reaction of tetrahydrofurancarbaldehyde 1 with the lithium and the magnesium derivatives of aromatic heterocycles.

Effective synthesis of C-nucleosides with 2′,4′-BNA modification

Hari, Yoshiyuki,Obika, Satoshi,Sakaki, Minako,Morio, Ken-Ichiro,Yamagata, Yuriko,Imanishi, Takeshi

, p. 3051 - 3063 (2007/10/03)

The effective synthesis of some C-nucleosides with 2′-O,4′-C-methylene bridged nucleic acid (2′,4′-BNA) modification was accomplished by using the coupling reaction of a tetrahydrofurancarbaldehyde 1 with the magnesium or lithium derivatives of aromatic heterocycles followed by the Mitsunobu cyclization. Moreover, it was clearly shown by 1H NMR spectra and X-ray crystallography that the sugar conformation in the synthesized C-nucleosides, independent of the nucleobases, was fixed in N-form.
