Check Digit Verification of cas no

The CAS Registry Mumber 1318779-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,8,7,7 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1318779-75:
(9*1)+(8*3)+(7*1)+(6*8)+(5*7)+(4*7)+(3*9)+(2*7)+(1*5)=197
197 % 10 = 7
So 1318779-75-7 is a valid CAS Registry Number.

Self-complementary quadruply hydrogen-bonded duplexes based on imide and urea units

Li, Xianghui,Fang, Yuyu,Deng, Pengchi,Hu, Jinchuan,Li, Tian,Feng, Wen,Yuan, Lihua

, p. 4628 - 4631 (2011/11/06)

The quadruply hydrogen-bonded duplexes based on an imide-urea structure preorganized by three-center hydrogen bonds were found to associate via bifurcated hydrogen bonds. 1H NMR dilution experiments revealed the high stability of the homodimer in apolar solvent (Kdim > 10 5 M-1 in CDCl3) and enhancement of association ability due to electron-withdrawing substituent effects. The ready synthetic availability and adjustable association affinity via electronic effects may render these association units potentially applicable in constructing supramolecular architectures.
