109270-58-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109270-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,7 and 0 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109270-58:
(8*1)+(7*0)+(6*9)+(5*2)+(4*7)+(3*0)+(2*5)+(1*8)=118
118 % 10 = 8
So 109270-58-8 is a valid CAS Registry Number.

Molecular Armatures. Synthesis and Structure of Troegers Base Analogues Derived from 4-, 2,4-, 3,4-, and 2,4,5-Substituted Aniline Derivatives

Sucholeiki, Irving,Lynch, Vincent,Phan, Ly,Wilcox, Craig S.

, p. 98 - 104 (2007/10/02)

The preparation of biomimetic systems designed to mimic natural receptor sites and enzymic active sites requires the development of new synthetic strategies for preparing large molecules with predictable and well-defined shapes.In this paper a number of derivatives of 6H,12H-5,11-methanodibenzodiazocines are prepared.The scope and limitations of the reaction of formaldehyde with aniline derivatives are examined.The molecules prepared have potential value as conformationally restricted armatures for the construction of biomimetic molecular systems.A crystallographic study reveals that the molecules are folded and that the angle formed by the two aryl rings ranges from 88 deg to 104 deg.Sulfonamides, bromides, alcohols, and amines can be introduced as side-chain substituents in these systems.
