Check Digit Verification of cas no

The CAS Registry Mumber 141788-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,8 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141788-62:
(8*1)+(7*4)+(6*1)+(5*7)+(4*8)+(3*8)+(2*6)+(1*2)=147
147 % 10 = 7
So 141788-62-7 is a valid CAS Registry Number.

Synthesis of podands bearing aromatic end groups and complex formation with tropylium tetrafluoroborate in 1,2-dichloroethane

Laemsae, Markku,Raitamaa, Kirsi,Pursiainen, Jouni

, p. 557 - 563 (2007/10/03)

A series of podands bearing phenyl, naphthyl and anthryl end groups were prepared and characterized. UV-visible spectrophotometry was used to investigate the host-guest chemistry of the podands in complexation with tropylium tetrafluoroborate in 1,2-dichloroethane. The results, are discussed and compared with those for previously studied systems containing crown ethers. The stability constants for these open-chain polyethers are in the range 5,1-8,4 dm3 mol-1, except for the podand having anthryl end groups [1,12 bis(anthryl-9)-2,5,8,11-tetraoxadodecane], which gives a 10-fold increase in the stability constant.
