Check Digit Verification of cas no
The CAS Registry Mumber 99341-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,4 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 99341-77:
(7*9)+(6*9)+(5*3)+(4*4)+(3*1)+(2*7)+(1*7)=172
172 % 10 = 2
So 99341-77-2 is a valid CAS Registry Number.

1,3,3-Trimethylbicyclo[2.2.1]heptan-2-endo-ol in Nucleophilic Substitution Reactions
Koval'skaya,Kozlov
, p. 1925 - 1927 (2007/10/03)
1,3,3-Trimethylbicyclo[2.2.1]heptan-2-endo-ol (fenchol) reacts with acetonitrile in the presence of sulfuric acid to selectively form an isofenchane derivative - N-acetyl-1,5,5-trimethylbicyclo[2.2.1]heptan-2-exo-amine as a result of nucleophilic addition at the most accessible carbon atom of a nonclassical 1,3,3-trimethylbicyclo[2.2.1]heptyl cation. The H2SO4-catalyzed reaction with acetic acid results in exclusive formation of 1,3,3-trimethylbicyclo[2.2.1]hept-2-exo-yl acetate, implying an SN2 reaction mechanism.
