Check Digit Verification of cas no

The CAS Registry Mumber 183197-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,1,9 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183197-80:
(8*1)+(7*8)+(6*3)+(5*1)+(4*9)+(3*7)+(2*8)+(1*0)=160
160 % 10 = 0
So 183197-80-0 is a valid CAS Registry Number.

Tetrahydrofuran Ring-Containing Nucleotide Analogs Related to HPMPA and PMEA

Liboska, Radek

, p. S72 - S75 (2007/10/03)

Synthesis of 9-N-(4-(phosphonomethoxy)tetrahydrofuran-3-yl)adenine derivatives, a novel type of nucleotide analogs related to (R)- and (S)-9-N-(3-hydroxy-2-phosphonomethoxypropyl)adenine ((R)- and (S)-HPMPA) and 9-(2-phosphonomethoxyethyl)adenine (PMEA), is described.The synthesis of adenine nucleotide analogs 6a-6d is based on the reaction of 6-N-protected adenine derivatives 5a-5d with diisopropyl tosyloxymethanephosphonate and subsequent deprotection of resulting compounds.The starting "nucleoside" derivatives have been prepared from chiral 4-benzyloxytetrahydrofuran-3-ols 3a-3d.
