Check Digit Verification of cas no

The CAS Registry Mumber 438044-17-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,8,0,4 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 438044-17:
(8*4)+(7*3)+(6*8)+(5*0)+(4*4)+(3*4)+(2*1)+(1*7)=138
138 % 10 = 8
So 438044-17-8 is a valid CAS Registry Number.

Enantioselective synthesis of 2-deoxy- and 2,3-dideoxyhexoses

Haukaas, Michael H.,O'Doherty, George A.

, p. 1771 - 1774 (2007/10/03)

The enantioselective syntheses of C-6 O-TBS- and N-Cbz-protected 2-deoxy- and 2,3-dideoxysugars have been achieved in 6-8 steps from furfural. A combination of chemo-, regio-, and diastereoselective oxidation and reduction reactions produced deoxysugars w

Enantioselective synthesis of N-Cbz-protected 6-amino-6-deoxymannose, -talose, and -gulose

Haukaas, Michael H.,O'Doherty, George A.

, p. 3899 - 3902 (2007/10/03)

equation presented The enantioselective synthesis of three 6-amino-6-deoxy sugars has been achieved in six to eight steps from furfural. A sequence of diastereoselective oxidation and reduction reactions produced Cbz-protected 6-aminomannose from furfuryl alcohol 3. The incorporation of a Mitsunobu reaction into the reaction sequence allows for the selective synthesis of both N-Cbz-protected 6-aminotalose and 6-aminogulose. The overall procedure allows for the synthesis of either enantiomer of these three aminosugars.
