Check Digit Verification of cas no

The CAS Registry Mumber 28239-05-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,3 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28239-05:
(7*2)+(6*8)+(5*2)+(4*3)+(3*9)+(2*0)+(1*5)=116
116 % 10 = 6
So 28239-05-6 is a valid CAS Registry Number.

New chiral organosulfur donors related to bis(ethylenedithio) tetrathiafulvalene

Yang, Songjie,Brooks, Andrew C.,Martin, Lee,Day, Peter,Pilkington, Melanie,Clegg, William,Harrington, Ross W.,Russo, Luca,Wallis, John D.

, p. 6977 - 6989 (2010)

Six new enantiopure chiral organosulfur donors, with structures related to BEDT-TTF, have been synthesised for use in the preparation of organic metals, starting either by double nucleophilic substitutions on the bis-mesylate of 2R,4R-pentane-2,4-diol or by a cycloaddition with subsequent elimination of acetic acid on the enol acetate of (+)-nopinone. Crystal structures of some of their radical cation triiodides salts and TCNQ complexes are reported.
