Check Digit Verification of cas no

The CAS Registry Mumber 200286-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,2,8 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 200286-21:
(8*2)+(7*0)+(6*0)+(5*2)+(4*8)+(3*6)+(2*2)+(1*1)=81
81 % 10 = 1
So 200286-21-1 is a valid CAS Registry Number.

Cesium fluoride-mediated claisen rearrangements of phenyl propargyl ethers: Substituent effects of an orthoalkoxy group on the benzene ring or modified propargyl residues

Ishikawa, Tsutomu,Mizutani, Akiko,Miwa, Chizue,Oku, Yumie,Komano, Naoko,Takami, Atsuya,Watanabe, Toshiko

, p. 2261 - 2272 (2007/10/03)

The expected 7-alkoxy-2-methylbenzo[b]furans were effectively given in the CsF-mediated Claisen rearrangement of phenyl propargyl ethers with an o-alkoxy substituent on the benzene ring. On the other hand CsF did not affect the production of the corresponding benzo[b]furans when ethers, carrying a propargyl residue modified by either 1,1-dimethyl or 3-ethoxycarbonyl functions, were used as substrates in the rearrangement.
