Check Digit Verification of cas no

The CAS Registry Mumber 73039-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,3 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 73039-79:
(7*7)+(6*3)+(5*0)+(4*3)+(3*9)+(2*7)+(1*9)=129
129 % 10 = 9
So 73039-79-9 is a valid CAS Registry Number.

Oxidation of Alkoxyphenols. Part 28. On the Configuration of 2,2'-Diphenoquinones

Hewgill, Frank R.,Greca, Bart La,Legge, Frank,Roga, Peter E.

, p. 131 - 134 (2007/10/02)

The n.m.r. spectra of a number of 2,2'-diphenoquinones imply that they have the trans-configuration.The importance of charge-separated structures in unsymmetrical quinones is discussed in relation to the formation of oxepinobenzofurans.
