Check Digit Verification of cas no

The CAS Registry Mumber 1408334-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,8,3,3 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1408334-01:
(9*1)+(8*4)+(7*0)+(6*8)+(5*3)+(4*3)+(3*4)+(2*0)+(1*1)=129
129 % 10 = 9
So 1408334-01-9 is a valid CAS Registry Number.

Quinone dimers are readily prepared quantitatively from 2- sulfanyl-1,4-dimethoxybenzene by oxidative treatment. The oxidative coupling progressed in a highly regioselective manner. Removal of O-protection and subsequent oxidation gave 5,5'- bis(sulfanylquinone) dimer in good yields. Physical properties of the dimer derivatives are also investigated.
