Check Digit Verification of cas no

The CAS Registry Mumber 189574-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,5,7 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 189574-94:
(8*1)+(7*8)+(6*9)+(5*5)+(4*7)+(3*4)+(2*9)+(1*4)=205
205 % 10 = 5
So 189574-94-5 is a valid CAS Registry Number.

Synthesis of radioiodinated carbocyclic cytosine analogues

Ahn, Hyunseok,An, Gwangil,Rhee, Hakjune

scheme or table, p. 1931 - 1935 (2012/01/05)

The synthesis of carbocyclic analogues of normal nucleosides has grown exclusively since they have shown potential antiviral and antitumor activities. Radiolabeled cis-1-[4-(hydroxy-methyl)-cyclopent-2-enyl]-5-[124I]- iodocytosine (carbocyclic d4IC) and cis-1-[4-(hydroxy-methyl)-cyclopent-2-enyl]- 5-(2-[124I]iodovinyl)cytosine (carbocyclic d4IVC) were synthesized. The synthetic route employed Pd(0)-catalyzed coupling reaction together with organotin and exchange reaction for radioiodination as key reactions. Carbocyclic [124I]d4IC gave more than 75% radiochemical yield with greater than 95% radiochemical purity. Carbocyclic [124I]d4IVC gave more than 80% radiochemical yield with greater than 95% radiochemical purity.
