Check Digit Verification of cas no

The CAS Registry Mumber 896507-37-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,6,5,0 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 896507-37:
(8*8)+(7*9)+(6*6)+(5*5)+(4*0)+(3*7)+(2*3)+(1*7)=222
222 % 10 = 2
So 896507-37-2 is a valid CAS Registry Number.

Oligoresorcinols fold into double helices in water

Goto, Hidetoshi,Katagiri, Hiroshi,Furusho, Yoshio,Yashima, Eiji

, p. 7176 - 7178 (2006)

We report the first double helices with a controlled helicity in water based on oligoresorcinols as a new, simplest water-soluble structural motif. The molecular strands of the oligoresorcinols self-assemble into double helices with the aid of aromatic interactions in water as characterized by 1H NMR and absorption spectroscopies together with the X-ray crystallographic study of the pentamer. The double helix formation is sensitive to the chain length, solvent composition, and temperature. Moreover, a bias in the screw sense of the double helices was achieved by covalently attaching chiral substituents to both ends of the molecular strands. Copyright
