Check Digit Verification of cas no
The CAS Registry Mumber 89-08-7 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89-08:
(4*8)+(3*9)+(2*0)+(1*8)=67
67 % 10 = 7
So 89-08-7 is a valid CAS Registry Number.

Separation of isomers of sulfophthalic acid by guest induced host framework formation with 4,4′-bipyridine
Mahata, Goutam,Roy, Sandipan,Biradha, Kumar
body text, p. 6614 - 6616 (2011/07/29)
The selective inclusion of aromatic guest molecules in host frameworks formed by 3-sulfophthalic acid or 4-sulfophthalic acid and 4,4′-bipyridine has been effectively utilized for the separation of sulfophthalic acid isomers.
