210689-29-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 210689-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,6,8 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 210689-29:
(8*2)+(7*1)+(6*0)+(5*6)+(4*8)+(3*9)+(2*2)+(1*9)=125
125 % 10 = 5
So 210689-29-5 is a valid CAS Registry Number.

Synthesis and biological activity of modified (2'-5')triadenylates containing 2'-terminal 2',3'-dideoxy-3'-fluoroadenosine derivatives

, p. 1278 - 1284 (2007/10/03)

Some new (2'-5')triadenylates 13-16, containing at the 2'-terminal end 3'-fluoro-2',3'-dideoxyadenosine derivatives, have been synthesized by the phosphotriester method. The selectively blocked nucleosides 2, 4, 5, and 7 were synthesized from the corresponding unprotected 'nucleosides 1, 3, and 6. The synthesized trimers 13 and 14 were 4- and 8-fold, respectively, more stable towards phosphodiesterase from Crotalus durissus than the natural trimer 17. In comparison to trimer 17 the new compounds 13-15 inhibit HIV-1 reverse transcriptase (RT) activity, and 15 and 16 the HIV-1 induced syncytia formation 2-3 fold whereas none of 13-16 can improve RNase L activity.
