134691-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134691-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134691-18:
(8*1)+(7*3)+(6*4)+(5*6)+(4*9)+(3*1)+(2*1)+(1*8)=132
132 % 10 = 2
So 134691-18-2 is a valid CAS Registry Number.

Synthesis and Thermal Reactions of Perfluoroalkylsulphonyl Substituted Ylides
Hackenberg, Juergen,Hanack, Michael
, p. 470 - 471 (2007/10/02)
The synthesis of several perfluoroalkylsulphonyl substituted ylides is described; thermal decomposition of the phenyliodonio(cyanononafluorobutylsulphonyl)methanide 3a in cyclohexene yields the bicycloheptane derivative, while the phenyliodoniobis(
