144489-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144489-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,8 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144489-81:
(8*1)+(7*4)+(6*4)+(5*4)+(4*8)+(3*9)+(2*8)+(1*1)=156
156 % 10 = 6
So 144489-81-6 is a valid CAS Registry Number.

Approach to the synthesis of annonaceous acetogenins from D-glucose
Bertrand,Gesson
, p. 5177 - 5180 (2007/10/02)
The preparation from D-glucose of threo-trans-threo and threo-cis-threo synthons 12 and 13 for the monochiral synthesis of mono (or eventually bis) tetrahydrofuran acetogenins is described. Their structure have been proven by degradation and comparison wi
