441799-32-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 441799-32-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,1,7,9 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 441799-32:
(8*4)+(7*4)+(6*1)+(5*7)+(4*9)+(3*9)+(2*3)+(1*2)=172
172 % 10 = 2
So 441799-32-2 is a valid CAS Registry Number.

An enaminone-directed benzannulation/macrocyclization approach to cyclophane ring systems

Pigge, F. Christopher,Ghasedi, Fatemeh,Rath, Nigam P.

, p. 4547 - 4552 (2007/10/03)

A straightforward and modular preparative approach to 1,3,5-triaroylbenzene-based functionalized cyclophane ring systems has been developed. The key cyclophane-forming macrocyclization reaction was accomplished during the course of a regioselective cross-benzannulation between bis(aryl ethynyl) ketone and enaminone reactants. Macrocyclic products with ring sizes ranging from 18-to 22-membered were successfully constructed. The composition of the tether connecting the two aryl ethynyl ketone fragments can be easily varied; consequently, this method is suitable for construction of a diverse range of structurally distinct cyclophane products. To illustrate this feature, cyclophanes possessing xylyl, alkyl, di(ethylene triamine), and di(ethylene oxy) bridging units were synthesized in isolated yields of 11-46%. Three new cyclophanes (calixarene-like macrocyles 8 and 9, as well as crownophane 18) were structurally characterized by X-ray diffractometry.
