Check Digit Verification of cas no

The CAS Registry Mumber 110371-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,3,7 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 110371-43:
(8*1)+(7*1)+(6*0)+(5*3)+(4*7)+(3*1)+(2*4)+(1*3)=72
72 % 10 = 2
So 110371-43-2 is a valid CAS Registry Number.

Four Isomeric 7-Isopropyloctahydro-4H-inden-4-ones

Matlin, Albert R.,Agosta, William C.

, p. 365 - 368 (1987)

The four isomeric 7-isopropyl-4-hydrindanones (2)-(5) have been prepared and their configurations assigned, using arguments based on the results of equilibration of the two pairs of ketones and on the products formed on hydrogenation of enone precursors.Base-catalysed equilibration at ca. 22 degC indicates that for (3)(2), -ΔG4.5 kcal mol-1 and for (5)(4), -ΔG ca. 0.1 kcal mol-1.Possible diagnostic features in the 1 H n.m.r. spectra of (2)-(5) are discussed briefly.
