71458-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71458-11-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,5 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71458-11:
(7*7)+(6*1)+(5*4)+(4*5)+(3*8)+(2*1)+(1*1)=122
122 % 10 = 2
So 71458-11-2 is a valid CAS Registry Number.

Fragmentation of the Chain in the Mass Spectra of the Pyrrolidides of Alkylcyclohexanecarboxylic Acids
Vetter, W.,Meister, W.
, p. 85 - 90 (1986)
The electron impact mass spectra of the pyrrolidides of both the cis- and trans-octylcyclohexanecarboxylic acids show the structure of the aliphatic chain, despite the steric hindrance of a direct H transfer from the chain to the functional group.
