Check Digit Verification of cas no

The CAS Registry Mumber 183617-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,6,1 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 183617-31:
(8*1)+(7*8)+(6*3)+(5*6)+(4*1)+(3*7)+(2*3)+(1*1)=144
144 % 10 = 4
So 183617-31-4 is a valid CAS Registry Number.

The Chemistry of 1,3,5-Triazacyclohexane Complexes, 4. Strained 1,3,5-Triazacyclohexane Complexes of Copper(I) and Copper(II)

Koehn, Randolf Dag,Seifert, Guido,Kociok-Koehn, Gabriele

, p. 1327 - 1334 (2007/10/03)

In this paper we report on the synthesis and the crystallographic characterization of η3-1,3,5-triazacyclohexane (R3TAC) complexes of copper(I) and copper(II).The complexes 2> (1), (2), Cu(PPh3)>(BF4) (3), and (BF4) (4) were characterized by X-ray crystallography.The highly strained and bent Cu-N bonds are longer than in the corresponding complexes of other amine ligands.One methylene carbon atom of the ring comes close to the copper atom (2.55 - 2.65 Angstroem).However, investigation of the ring deuterated complexes by IR and X-ray crystallography (6>2) showed no clear evidence for attractive C-H-Cu interactions. - Keywords: Triazacyclohexanes; Copper complexes; Triphenylphosphane
