370069-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 370069-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,0,0,6 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 370069-67:
(8*3)+(7*7)+(6*0)+(5*0)+(4*6)+(3*9)+(2*6)+(1*7)=143
143 % 10 = 3
So 370069-67-3 is a valid CAS Registry Number.

Structural, spectroscopic and electrochemical studies of nickel(II) "sandwich" complexes with ligands featuring tethered 1,4,7-triazacyclononane macrocycles

X-Ray structure determinations of bromo and/or bromomethylsubstituted benzenes: C-H···Br, C-Br···Br, and C-Br···p interactions

Jones, Peter G.,Kus, Piotr,Dix, Ina

, p. 1273 - 1281 (2013/02/23)

The structures of seven benzene derivatives [1,2,3-tri(bromomethyl)benzene, (1); 3,5-di(bromomethyl)bromobenzene, (2); 2,5-di(bromomethyl)bromobenzene, (3); 4-(bromomethyl)-2,5-dibromotoluene, (4); 4-(bromomethyl)bromobenzene, (5); 2,3-di(bromomethyl)bromobenzene, (6) and (bromomethyl)-p-dibromobenzene, (7)] with bromo and bromomethyl (and in one case methyl) substituents are presented and analysed in terms of Br···Br interactions up to 4.0 A , supported by hydrogen bonds H···Br. Some interactions of the type Br···π and π·· · π are encountered and play a subordinate role in the packing. Despite the close chemical similarity of the compounds, some of which are isomers with permuted substituent positions, the packing motifs are highly variable. Compounds 2-5 are based on layer structures with Brn (n=3, 4) and/or mixed Br/C rings. Compounds 1, 6 and 7 display three-dimensional packings of differing complexity, but with interpretable substructures; 1 can be analysed in terms of ribbons of linked Br3 and Br4 rings; 6 displays chains of linked Br3 triangles; 7 consists of ribbons of linked Br4 quadrilaterals.
