16554-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16554-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,5,5 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 16554-81:
(7*1)+(6*6)+(5*5)+(4*5)+(3*4)+(2*8)+(1*1)=117
117 % 10 = 7
So 16554-81-7 is a valid CAS Registry Number.

The Pressure Effect on the 1,5-Sigmatropic Hydrogen Shift of Tropylidene Derivative, 3,3-Diphenyl-3,3a-dihydrocycloheptafuran-2-one

Sugiyama, Shigeru,Takeshita, Hitoshi

, p. 1203 - 1204 (2007/10/02)

The 1,5-sigmatropy of 3,3-diphenyl-3,3a-dihydrocyclohepta-furan-2-one was examined in dibutyl ether to 1600 bar at 130 deg C.The rearrangement was slightly accelerated with pressure, and was different to the pressure effect of 1,5-sigmatropy of cyclopentadienes.The activation volume was in the range of the concerted process, but its transition state was as loose as those biradical-like.
