Calculate Digit Verification of CAS Registry Number 158226-24:
(8*1)+(7*5)+(6*8)+(5*2)+(4*2)+(3*6)+(2*2)+(1*4)=135
135 % 10 = 5
So 158226-24-5 is a valid CAS Registry Number.

Synthesis of a potential antiviral compound: 5-Bromoethynyl-2'- deoxyuridine

Eger,Jalalian,Schmidt

, p. 8371 - 8380 (1994)

5-Bromoethynyluracil and its deoxyriboside can be prepared in good yields starting from dibromovinyluracil, which is accesible by literature methods. 5-Bromoethynyl-deoxyuridine is less effective against HSV-1 than E- (bromovinyl)-deoxyuridine but, similar to BVDU, seems to exhibit a certain selectivity toward HSV-1. Molecular calculations prove the spatial similarity of both compounds.
