87892-94-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87892-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,9 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 87892-94:
(7*8)+(6*7)+(5*8)+(4*9)+(3*2)+(2*9)+(1*4)=202
202 % 10 = 2
So 87892-94-2 is a valid CAS Registry Number.

An Investigation of the Chemistry of Phenylsulphonylcyclopentadiene
Bridges, Alexander J.,Fischer, John W.
, p. 2359 - 2364 (2007/10/02)
Phenylsulphonylcyclopentadiene (7) exists mainly as the 1-isomer, and the assigned structure of its dimer (6) has been corroborated by n.m.r. decoupling experiments.Both the diene (7) and its cyclopentadienide anion (8) were unusually unreactive, although
