78134-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78134-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,3 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78134-81:
(7*7)+(6*8)+(5*1)+(4*3)+(3*4)+(2*8)+(1*1)=143
143 % 10 = 3
So 78134-81-3 is a valid CAS Registry Number.

, p. 557 - 558 (2007/10/02)
For the first time a perfluoroalkanesulfonylallene, the 1-phenyl-3-(trifluoromethanesulfonyl)-propadiene (5) was synthesized. 5 is formed directly when phenylpropinyltrifluoromethanesulfide 4 is oxidized with p-nitroperbenzoic acid. 5 reacts already at ro
