161452-63-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 161452-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,4,5 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 161452-63:
(8*1)+(7*6)+(6*1)+(5*4)+(4*5)+(3*2)+(2*6)+(1*3)=117
117 % 10 = 7
So 161452-63-7 is a valid CAS Registry Number.

Nucleosides and nucleotides. 132. Synthesis and biological evaluations of ring-expanded oxetanocin analogues: Purine and pyrimidine analogues of 1,4-anhydro-2-deoxy-D-arabitol and 1,4-anhydro-2-deoxy-3-hydroxymethyl-D-arabitol

(2R)-2-C-(Adenin-9-yl)- 1,4-anhydro-2-deoxy-D-arabitol (2) and (2R, 3R)-2-C-(adenin-9-yl)- 1,4-anhydro- 2,3-dideoxy-3-C-hydroxymethyl-D-arabitol (3), and their 2,6-diaminopurine analogues 4 and 5 were synthesized from corresponding 1,4-anhydro-D-ribitol derivatives, which were readily obtained from D-glucose. The corresponding guanine isonucleosides 6 and 7 were obtained from 4 and 5 by enzymatic deamination with adenosine deaminase. Pyrimidine counterparts 8 and 9 were synthesized via construction of the pyrimidine moiety from amino derivatives of the 1,4-anhydro-D-arabitol derivatives. Antiviral activity of these ring-expanded derivatives of oxetanocins towards HSV-1, HSV-2, HCMV, and HBV in vitro was examined along with their cytotoxicity against L1210 and KB cells in vitro.
