128015-91-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128015-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,1 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128015-91:
(8*1)+(7*2)+(6*8)+(5*0)+(4*1)+(3*5)+(2*9)+(1*1)=108
108 % 10 = 8
So 128015-91-8 is a valid CAS Registry Number.

Pd-catalyzed decarbonylative olefination of aryl esters: Towards a waste-free Heck reaction

Goossen, Lukas J.,Paetzold

, p. 1237 - 1241 (2007/10/03)

Easy and clean: A palladium (0)-catalyzed decarbonylative Heck olefination of activated esters of aryl, heteroaryl, and vinyl carboxylic acids opens up an opportunity for a novel waste-free Heck olefination process (see scheme).

ON THE NATURE OF RESONANCE INTERACTIONS IN SUBSTITUTED BENZENES. II. 13C NMR INVESTIGATIONS ON ARYL 4-X-BENZOATES

Dell'Erba, Carlo,Sancassan, Fernando,Leandri, Giuseppe,Novi, Marino,Petrillo, Giovanni,et al.

, p. 643 - 648 (2007/10/02)

The response of the carbonyl-carbon chemical shift to the substituent effect in aryl 4-X-benzoates 3-6 has been studied in CDCl3.The comparison with relevant data for methyl benzoates 1 and acetophenones 2 shows, along the 3-to-6 sequence, a gradual shift
