220845-66-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220845-66-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,4 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 220845-66:
(8*2)+(7*2)+(6*0)+(5*8)+(4*4)+(3*5)+(2*6)+(1*6)=119
119 % 10 = 9
So 220845-66-9 is a valid CAS Registry Number.

Novel preparation of cis,cis-trisubstituted cyclopropane nucleosides
Gauvry, Noelle,Huet, Francois
, p. 1321 - 1328 (2007/10/03)
Novel cyclopropane nucleosides, cis-2',cis-3'- bis(hydroxymethyl)cyclopropyl thymine 4a and adenine 4b were synthesized. The stereoselective ring contraction of cyclobutyl bromohydrin 8 afforded cyclopropyl aldehyde 9 with a cis,cis configuration. After o
