Check Digit Verification of cas no

The CAS Registry Mumber 123765-12-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,6 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123765-12:
(8*1)+(7*2)+(6*3)+(5*7)+(4*6)+(3*5)+(2*1)+(1*2)=118
118 % 10 = 8
So 123765-12-8 is a valid CAS Registry Number.

Transoid Homoallylic Proton-Proton Coupling Constants

Barfield, Michael,Spear, Robert J.,Sternhell, Sever

, p. 659 - 664 (2007/10/02)

Transoid homoallylic coupling constants (5JH,H) for six compounds (5,10-dihydroindenoindene and confertifolin derivatives) of fixed stereochemistry were determined and compared with calculated values.Magnetic equivalence limited discrete determination of 5Jtrans and 5Jcis to three of these compounds.The single compound where unequivocal assignment could be made revealed 5Jtrans > 5Jcis; this was supported in two other compounds by tentative assignment.Changes in the magnitude of the couplings suggested that substantial substituent effects may be operative.INDO-MO calculations correctly predicted the angular dependence but incorrectly predicted 5Jcis > 5Jtrans.
