Check Digit Verification of cas no

The CAS Registry Mumber 287933-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,7,9,3 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 287933-70:
(8*2)+(7*8)+(6*7)+(5*9)+(4*3)+(3*3)+(2*7)+(1*0)=194
194 % 10 = 4
So 287933-70-4 is a valid CAS Registry Number.

Synthesis and biological activity of a series of methylene-expanded oxetanocin nucleoside analogues

Jung, Michael E.,Toyota, Akemi,De Clercq, Erik,Balzarini, Jan

, p. 499 - 520 (2007/10/03)

A series of methylene-expanded oxetanocin nucleoside analogues, e.g. analogues of 2 and the known antiviral nucleosides AZT, FLT, and ddC (3) were prepared by a very direct route beginning with the readily available (S)-glycidol 4 and proceeding via the dihydrofuran-3-methanols 9a,b. Biological testing of these modified nucleosides indicates that they are non-cytotoxic compounds with generally weak antiviral activity. However, the guanosine analogue 2G showed pronounced activity vs. herpes simplex virus type 1 (HSV-1) in cell culture and was HSV-1-encoded thymidine kinase dependent. This compound is therefore an interesting new lead structure for the development of new anti-HSV agents.
