Check Digit Verification of cas no

The CAS Registry Mumber 100084-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,0,8 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100084-13:
(8*1)+(7*0)+(6*0)+(5*0)+(4*8)+(3*4)+(2*1)+(1*3)=57
57 % 10 = 7
So 100084-13-7 is a valid CAS Registry Number.

Directed Synthesis of Translationally Isomeric -Catenanes

Rissler, Klaus,Schill, Gottfried,Fritz, Hans,Vetter, Walter

, p. 1374 - 1399 (2007/10/02)

In a multi-step reaction sequence the tetrahydroxymetacyclophane 12c is synthesized.Acetalisation with 1,25-dichloro-13-pentacosanone followed by nitration and reduction afforded the diamine 13c.By cyclization of this compound in 2-pentanol with sodium carbonate and sodium iodide under high dilution conditions the monomeric products 16, 17, and 18 are obtained in yields of 21.4, 7.7, and 0,9percent, respectively.On the basis of mass, 13C NMR and 1H NMR spectra the structure of these compounds is discussed.Starting from the precatenane 16 the -catenanes 25a,b,c and 26a,b,c are obtained in a multi-step reaction sequence.The structure of these compounds is confirmed by mass, 13C NMR, and 1H NMR spectroscopic investigations.
