Check Digit Verification of cas no

The CAS Registry Mumber 4729-06-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 4729-06:
(6*4)+(5*7)+(4*2)+(3*9)+(2*0)+(1*6)=100
100 % 10 = 0
So 4729-06-0 is a valid CAS Registry Number.

An efficient synthesis of (±)-cis-2-mino-6-hydroxy-9[4'-hydroxyethyl- 2'-cyclopenten-1'-yl]purine

Kim, Won,Kim, Hyangdug,Rhee, Hakjune

, p. 219 - 224 (2007/10/03)

The synthesis of a carbovir analogue, (±)-cis-2-amino-6-hydroxy-9- [4'hydroxyethyl-2'-cyclopenten-l'-yl]purine (2) was achieved from 2,5- norbornadiene (3) in six steps and 31% overall yield. This route involves a Meinwald rearrangement, one-pot operation (acid-hydrolysis and subsequent sodium borohydride reduction), and a Pd(0)catalyzed coupling reaction.
