Check Digit Verification of cas no

The CAS Registry Mumber 215385-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,3,8 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 215385-47:
(8*2)+(7*1)+(6*5)+(5*3)+(4*8)+(3*5)+(2*4)+(1*7)=130
130 % 10 = 0
So 215385-47-0 is a valid CAS Registry Number.

Efficient synthesis of functionalized [7]helicenes

Fox, Joseph M.,Goldberg, Naomi R.,Katz, Thomas J.

, p. 7456 - 7462 (1998)

[7]Helicenebisquinones can be made easily and in quantity by reacting the silyl enol ethers of a 9,10-dialkoxy-, or better a 9,10-disiloxy-, 3,6-diacetylphenanthrene, with p-benzoquinone. If an ethyl enol ether is used in place of the silyl enol ether, the transformation proceeds in much lower yield. The [7]helicenes are efficiently resolved into their enantiomers, and absolute configurations are assigned.
