Check Digit Verification of cas no

The CAS Registry Mumber 98678-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,7 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 98678-39:
(7*9)+(6*8)+(5*6)+(4*7)+(3*8)+(2*3)+(1*9)=208
208 % 10 = 8
So 98678-39-8 is a valid CAS Registry Number.

Electrochemical generation and reaction of o-quinodimethanes from {[[2-(2,2-dibutyl-2-stannahexyl)phenyl]-methyl]thio} benzenes

Jinno, Madoka,Kitano, Yoshikazu,Tada, Masahiro,Chiba, Kazuhiro

, p. 435 - 437 (2008/02/12)

(equation presented) The anodic oxidation of {[[2-(2,2-dibutyl-2-stannahexyl)phenyl]methyl]thio}benzenes gave o-quinodimethanes which were trapped in situ by dienophiles to give the corresponding cycloadducts in excellent yields. The electron transfer and succeeding 1,4-elimination reaction was efficiently completed in a solution of lithium perchlorate/nitromethane in the presence of acetic acid. The reaction progress was quantitatively controlled by the passage of charge. By using this new method, an aryltetralin lignan skeleton was also synthesized.

Stereoselectivity in the Diels-Alder Reaction of Phenyl- and Oxy-Substituted o-Quinodimethanes

Durst, Tony,Kozma, Elisabeth C.,Charlton, James L.

, p. 4829 - 4833 (2007/10/02)

Phenyl-, methoxy-, and acetoxy-substituted o-quinodimethanes (o-QDM) have been added to dimethyl fumarate and maleate to determine the stereoselectivity of the addition reaction.The o-QDM's were generated from the corresponding 1,3-dihydrobenzothiophen
