Check Digit Verification of cas no

The CAS Registry Mumber 200420-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,4,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200420-91:
(8*2)+(7*0)+(6*0)+(5*4)+(4*2)+(3*0)+(2*9)+(1*1)=63
63 % 10 = 3
So 200420-91-3 is a valid CAS Registry Number.

A series of 5-keto-substituted 7-tert-butyl-2,3-dihydro-3,3- dimethylbenzofurans (DHDMBFs) were found to be nonsteroidal antiinflammatory and analgesic agents. These compounds are inhibitors of 5-1ipoxygenase (5- LOX) and cyclooxygenase (COX) with selectivity for the COX-2 isoform. A series of analogues were prepared to investigate the scope of this lead. Five ketone side chains from active DHDMBFs were used to investigate the effects of changes in the DHDMBF 'core': the size and identity of the heterocycle and the substituent requirements of the heterocycle and phenyl ring. Biological testing showed that a variety of structural changes can be accommodated, but no structure was clearly superior to the DHDMBF structure.
