Check Digit Verification of cas no

The CAS Registry Mumber 117934-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,9,3 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 117934-75:
(8*1)+(7*1)+(6*7)+(5*9)+(4*3)+(3*4)+(2*7)+(1*5)=145
145 % 10 = 5
So 117934-75-5 is a valid CAS Registry Number.

SYNTHESIS AND CONFORMATIONAL PROPERTIES OF DIIMIDAZOLOMETACYCLOPHANE AND HOMOLOGS

Sasaki, Hideaki,Kitagawa, Tokujiro

, p. 1593 - 1596 (2007/10/02)

Diimidazolometacyclophane (5a), a novel metacyclophane-diene (4) derivative, was synthesized by the ring transformation of the oxazole ring of dioxazolometacyclophane (1a) to imidazole rings.On the basis of proton nuclear magnetic resonance ((1)H-NMR) spectroscopy, the preferred conformation of 5a in solution at room temperature could be assigned as a syn form. - KEYWORDS - cyclophane; metacyclophane; metaparacyclophane; ring transformation; oxazole; imidazole; conformational analysis
