749900-28-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 749900-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,9,0 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 749900-28:
(8*7)+(7*4)+(6*9)+(5*9)+(4*0)+(3*0)+(2*2)+(1*8)=195
195 % 10 = 5
So 749900-28-5 is a valid CAS Registry Number.

THE CHEMISTRY OF PHTALIDE-3-CARBOXYLIC ACID - I DECARBOXYLATION ON THE PRESENCE OF THE ALDEHYDES

Prager, Rolf H.,Schiesser, Carl H.

, p. 1517 - 1522 (1984)

The decarboxylation of phthalide-3-carboxylic acid (3-oxo-1,3-dihydroisobenzofuran-1-carboxylic acid) has been studied in the melt, in dimethylsulfoxide, and in the presence of aromatic aldehydes.The latter are efficiently trapped to produce mixtures of 3-arylidene-phthalides and 3-(arylhydroxymethyl)phthalides.Kinetic and other evidence supports the proposal that this reaction occurs in a tight cyclic transition state.
