58728-89-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58728-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,7,2 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58728-89:
(7*5)+(6*8)+(5*7)+(4*2)+(3*8)+(2*8)+(1*9)=175
175 % 10 = 5
So 58728-89-5 is a valid CAS Registry Number.

Rearrangements of 5,5,6,6-Tetraalkyl-2-norbornyl Cations
Kirmse, Wolfgang,Mrotzeck, Uwe,Siegfried, Rainer
, p. 241 - 245 (2007/10/02)
When the 6,6-dimethyl-2-norbornyl cation (9) is generated from the tosylhydrazone 5 by way of the diazonium ion 8, a 2H label is distributed equally between positions 1 and 2 of the exo-alcohol 10.The degeneracy of 9, previously derived from solvolytic st
