Check Digit Verification of cas no

The CAS Registry Mumber 19305-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,3,0 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19305-95:
(7*1)+(6*9)+(5*3)+(4*0)+(3*5)+(2*9)+(1*5)=114
114 % 10 = 4
So 19305-95-4 is a valid CAS Registry Number.

STERIC REPULSION AND INTRAMOLECULAR INTERACTION OF SUBSTITUENTS IN 4-SUBSTITUTED ADAMANTAN-2,6-DIONES

Duddeck, Helmut

, p. 1365 - 1370 (2007/10/02)

By (13)C NMR measurements in presence of Yb(dpm)3 all (13)C signals of the title compounds 2-6 were assigned.Ratios of "bounds shifts" (Ri/j) can be correlated with Voegtle's n-values and reflect the spatial requirement of the substituent, unless the substituent participates significantly in complexation with Yb(dpm)3.Effects of intramolecular substituent interactions of different types within one molecule are additive, i.e. the individual interactions mechanisms are acting more or less independently.
