Check Digit Verification of cas no

The CAS Registry Mumber 1042065-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,0,6 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1042065-80:
(9*1)+(8*0)+(7*4)+(6*2)+(5*0)+(4*6)+(3*5)+(2*8)+(1*0)=104
104 % 10 = 4
So 1042065-80-4 is a valid CAS Registry Number.

An efficient and highly diastereoselective synthesis of C-glycosylated 1,3-oxazolidines from N-methyl-d-glucamine

Martínez, R. Fernando,ávalos, Martín,Babiano, Reyes,Cintas, Pedro,Jiménez, José L.,Light, Mark E.,Palacios, Juan C.,Pérez, Esther M.S.

, p. 6377 - 6386 (2008/09/21)

A one-pot procedure for preparing chiral 1,3-oxazolidines derived from N-methyl-d-glucamine and aryl aldehydes is described. It has been carried out by using readily available reagents and operationally simple conditions allowing the preparation of the acyclic C-nucleoside analogs in high yields. The structure of these derivatives has been fully characterized by NMR correlations and single-crystal X-ray diffraction. Some reactions also provide access to the corresponding tetrahydro-1,3-oxazines by an alternative ring closure. Mechanistic considerations account for the observed steric course. Crown Copyright
