132998-36-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132998-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,9 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132998-36:
(8*1)+(7*3)+(6*2)+(5*9)+(4*9)+(3*8)+(2*3)+(1*6)=158
158 % 10 = 8
So 132998-36-8 is a valid CAS Registry Number.

Perfluoro-enolate chemistry: An 'electrophile-coexisting' procedure for carbon-carbon bond forming reactions with an ester lithium F-enolate
Qian,Nakai
, p. 7043 - 7046 (2007/10/02)
A novel 'electrophile-coexisting' procedure is developed for effecting aldol reactions and Michael additions with the lithium F-enolate of ethyl tetrafluoropropionate without appreciable occurrence of defluorination from the F-enolate.
