Check Digit Verification of cas no
The CAS Registry Mumber 57398-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,3,9 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 57398-28:
(7*5)+(6*7)+(5*3)+(4*9)+(3*8)+(2*2)+(1*8)=164
164 % 10 = 4
So 57398-28-4 is a valid CAS Registry Number.

Synthesis of the ansa-bridged benzofuranquinone (+/-)-tridentoquinone (+/-)-(1) is approached by constriction of a C4 methyl ketone chain at the 3-position of 6-bromo-4,5,7-trimethoxy-2,2-dimethyl-2,3-dihydrobenzofuran (10) and alkylation at its 6-position leading after modification to a dimethyl C10 aldehydic chain.Closure of the ansa bridge by McMurry coupling of the aldehyde and ketone groups of the intermediate (33) with C8K/TiCl3 appears to occur, but in poor yield and with uncertain stereochemistry, and the synthesis has not been completed.
