Check Digit Verification of cas no

The CAS Registry Mumber 81649-89-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,4 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81649-89:
(7*8)+(6*1)+(5*6)+(4*4)+(3*9)+(2*8)+(1*9)=160
160 % 10 = 0
So 81649-89-0 is a valid CAS Registry Number.

THE SYNTHESIS AND CONFORMATIONAL BEHAVIOUR OF 2,11-DITHIAMETACYCLOPHANES WITH INTERNAL PHENYL SUBSTITUENTS.

Mitchell, Reginald H.,Anker, Willem

, p. 5135 - 5138 (2007/10/02)

The synthesis of syn- and anti-9-methyl-18-phenyl- and anti-9,18-diphenyl-2,11-dithiametacyclophanes is described, together with their variable temperature 1Hmr spectra.Only partial rotation of the phenyl substituents (ΔGc50 kJ./mol) is believed to occur.
