114091-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114091-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,0,9 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 114091-81:
(8*1)+(7*1)+(6*4)+(5*0)+(4*9)+(3*1)+(2*8)+(1*1)=95
95 % 10 = 5
So 114091-81-5 is a valid CAS Registry Number.

STEREOSELECTIVE ADDITION OF A NOVEL, ENANTIOMERICALLY PURE VINYLLITHIUM REAGENT TO PROCHIRAL CARBONYL COMPOUNDS
Mahler, Hellmut,Braun, Manfred
, p. 5145 - 5148 (1987)
The vinyllithium reagent (S)-3, generated from the alkene 6 by bromine/lithium exchange, reacts stereoselectively with prochiral carbonyl compounds.Debromination of the adducts 4/8 affords the (Z)-olefins 11/12, which can be cleaved by ozonolyzis.
