Check Digit Verification of cas no

The CAS Registry Mumber 16838-89-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,3 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 16838-89:
(7*1)+(6*6)+(5*8)+(4*3)+(3*8)+(2*8)+(1*9)=144
144 % 10 = 4
So 16838-89-4 is a valid CAS Registry Number.

Novel pyrrole C-nucleosides by nitrogen extrusion from pyridazine C-nucleosides

Joshi, Uday,Josse, Solen,Pipelier, Muriel,Chevallier, Floris,Pradère, Jean-Paul,Hazard, Roland,Legoupy, Stéphanie,Huet, Fran?ois,Dubreuil, Didier

, p. 1031 - 1033 (2004)

Pyridazine C-nucleosides have been synthesized by [4+2] cycloaddition of alkynyl C-nucleosides with substituted tetrazines. These pyridazines on extrusion of a nitrogen atom afforded novel pyrrole C-nucleosides with good yields. The results of electrochemical and chemical reduction are compared.
