26880-35-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26880-35-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,8 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26880-35:
(7*2)+(6*6)+(5*8)+(4*8)+(3*0)+(2*3)+(1*5)=133
133 % 10 = 3
So 26880-35-3 is a valid CAS Registry Number.

Reaction of O-Acyl-1,4-benzoquinone Monooximes with Cyclopentadiene
Avdeenko, A. P.,Glinyanaya, N. M.,Pirozhenko, V. V.
, p. 1066 - 1070 (2007/10/03)
Addition of cyclopentadiene to unsubstituted O-acyl-1,4-benzoquinone monooximes or their 2- or 3-methyl derivatives across the double bond of the quinone ring yielded the only endo-Z isomer, in spite of the possibility for isomerization around the C=N bon
