109978-98-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109978-98-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109978-98:
(8*1)+(7*0)+(6*9)+(5*9)+(4*7)+(3*8)+(2*9)+(1*8)=185
185 % 10 = 5
So 109978-98-5 is a valid CAS Registry Number.

DNG cytidine: Synthesis and binding properties of octameric guanidinium-linked deoxycytidine oligomer

Szabo, Istvan E.,Bruice, Thomas C.

, p. 4233 - 4244 (2007/10/03)

The synthesis of guanidinium-linked cytidyl oligomer (DNG-C8), a cationic DNA analog, and the corresponding cytidine monomers is described. The DNG monomer synthesis was streamlined to produce a shorter route to the final monomer than previously reported for thymidine and subsequent solid-phase synthesis produced an octameric cytidyl DNG strand. Because octameric deoxyguanosine would be used as the complementary strand in our studies, it was necessary to investigate guanosine self-association. Singular value decomposition was used to mathematically deconvolve the spectral data and confirm the presence of transitions due to DNA-G8 self-association. Job plots show the binding stoichiometry of DNG-C8 with DNA-G 8 to be 1:1. Thermal denaturation studies of the DNG-C 8·DNA-G8 duplex established a T m≥90°C and a ΔG°=-13.3kcalmol-1, indicating the DNG-C8·DNA-G8 duplex is over 1000 times more stable than that of DNA-C8·DNA-G8.
