Check Digit Verification of cas no
The CAS Registry Mumber 289660-11-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,6,6 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 289660-11:
(8*2)+(7*8)+(6*9)+(5*6)+(4*6)+(3*0)+(2*1)+(1*1)=183

A facile access to 2-deoxy-L-ribose
Fazio, Fabio,Schneider, Manfred P.
, p. 2143 - 2145 (2007/10/03)
The title compound was prepared in five steps starting from R-(+)-5-benzyloxymethyl-5H-furan-2-one 1 via syn-dihydroxylation of its double bond, regioselective tosylation of the 2-OH group in the thus obtained diol 2 followed by selective deoxygenation of that position.
