Check Digit Verification of cas no

The CAS Registry Mumber 191106-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,1,0 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 191106-49:
(8*1)+(7*9)+(6*1)+(5*1)+(4*0)+(3*6)+(2*4)+(1*9)=117
117 % 10 = 7
So 191106-49-7 is a valid CAS Registry Number.

An optimized palladium catalyzed cross-coupling of nonracemic trifiuoromethylsulfonyl and fluorosulfonyl enol ethers to arylboronic acids

Pridgen, Lendon N.,Huang, G. Kris

, p. 8421 - 8424 (1998)

Several trifluoromethylsulfonyl and fluorosulfonyl nonracemic (> 99% e.e.) enol ethers were cross-coupled to arylboronic acid under palladium [PdCl2(dppf)] catalysis to provide in high yield (>98%) selected 1,3-diaryl nonracemic indenes.
