Check Digit Verification of cas no

The CAS Registry Mumber 71020-48-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,2 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71020-48:
(7*7)+(6*1)+(5*0)+(4*2)+(3*0)+(2*4)+(1*8)=79
79 % 10 = 9
So 71020-48-9 is a valid CAS Registry Number.

Fluoride ion catalyzed alkylation of purines, pyrimidines, nucleosides and nucleotides using alky halides.

Ogilvie,Beaucage,Gillen,Entwistle,Quilliam

, p. 1695 - 1708,1696, 1703 (1979)

Alkyl halides react rapidly with purines and pyrimidines in the presence of fluoride ion. Alkylation of thymidine leads to novel dimeric nucleoside derivatives bridged through N3. Alkylation of thymidine mono and dinucleotides leads to alkylation at the base (N3) as well as diester and triester formation at the phosphate.
