945971-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 945971-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,9,7 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 945971-89:
(8*9)+(7*4)+(6*5)+(5*9)+(4*7)+(3*1)+(2*8)+(1*9)=231
231 % 10 = 1
So 945971-89-1 is a valid CAS Registry Number.

Paracyclophanes. Part 58 [1]. On the use of the stilbene-phenanthrene photocyclization in [2.2]paracyclophane chemistry

Hopf,Hucker,Ernst

, p. 947 - 969 (2008/09/17)

The application of the stilbene→phenanthrene photocyclization to [2.2]paracyclophane chemistry has been investigated. For the model system 4-styryl[2.2]paracyclophane (2) to [2.2]phenanthrenoparacyclophane (3) the reaction allows the introduction of alkyl substituants in the 6-, 7-, 8- and 9-position of the phenanthrene moiety. However, when the substituent in the 9-position (bay area of phenanthrene nucleus) becomes too large, viz. tert-butyl, no ring closure is observed anymore. The side products of the process (ring cleavage products of the cyclophane core such as 9 and 10) have been characterized for the first time. Extension of the condensed deck is possible leading to PAH-phanes as demonstrated by the preparation of the chrysenophanes 45 and 60; the cyclization to novel helicenophanes such as 50 also takes place without difficulties. In the case of 1,2-di(4-[2.2] paracyclophanyl)ethene (63) the triply-layered hydrocarbon 65 is produced on irradiation in small amounts.
