75773-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75773-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,7,7 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 75773-20:
(7*7)+(6*5)+(5*7)+(4*7)+(3*3)+(2*2)+(1*0)=155
155 % 10 = 5
So 75773-20-5 is a valid CAS Registry Number.

Total Synthesis of 2,5-Diamino-2,5-dideoxyribose
Schmidt, Richard R.,Scheibe, Raimund
, p. 1307 - 1320 (2007/10/02)
The enantiomeric 2,5-diacetylamino-2,5-dideoxyriboses 11A and 11B are obtained via cycloaddition of diacylazo compounds with 2,4-pentadienal acetal 2 and diastereoselective cis-dihydroxylation of the cycloadducts 3a-c in a few steps.Resolution of the race
