Check Digit Verification of cas no
The CAS Registry Mumber 130703-07-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,0 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130703-07:
(8*1)+(7*3)+(6*0)+(5*7)+(4*0)+(3*3)+(2*0)+(1*7)=80
80 % 10 = 0
So 130703-07-0 is a valid CAS Registry Number.

Improved procedure for the regiospecific synthesis of 2'-deoxyribonucleosides
Baud,Chavis,Lucas,Imbach
, p. 4437 - 4440 (1990)
2'-Deoxyribonucleosides are regiospecifically synthesized in high yields by catalyzing with KI-dibenzo-18-crown-6 PTC the condensation between unprotected silylated purines and pyrimidines and the appropriate easily available 2-deoxy-ribofuranosyl or pyranosyl sugar derivatives.
