Check Digit Verification of cas no
The CAS Registry Mumber 7197-62-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7197-62:
(6*7)+(5*1)+(4*9)+(3*7)+(2*6)+(1*2)=118
118 % 10 = 8
So 7197-62-8 is a valid CAS Registry Number.

Synthesis of spirobiindanes via bis-cyclization reaction of the 1,5-diaryl-3-pentanones catalyzed by heteropoly acids
Lan, Kun,Shan, Zixin,Fan, Shao
, p. 4343 - 4345 (2007/10/03)
Bis-cyclization reaction of the 1,5-diaryl-3-pentanones catalyzed by heteropoly acids (HPAs) was examined for the first time, and a series of spirobiindanes were synthesized. 1,5-Diaryl-3-pentanones were refluxed and dehydrated in toluene in the presence of 0.15 equiv of a heteropoly acid to furnish spirobiindanes in moderate to high yield. For the known 4,4′-dibromo-7,7′-dimethoxy-1,1′-spirobiindane, the yield was upgraded from 66% to 80%.
