3257-05-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3257-05-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,5 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3257-05:
(6*3)+(5*2)+(4*5)+(3*7)+(2*0)+(1*5)=74
74 % 10 = 4
So 3257-05-4 is a valid CAS Registry Number.

The Wittig Reaction with Glutaric and Succinic Anhydrides

Abell, Andrew D.,Doyle, Ian R.,Massy-Westropp, Ralph A.

, p. 2277 - 2287 (2007/10/02)

Six-membered cyclic anhydrides, including glutaric and some of its alkylated derivatives, have been shown to yield enol-lactones with ethoxycarbonylmethylenetriphenylphosphorane; the (E) isomer is formed preferentially.The reactions of methyl-substituted succinic anhydrides with the same phosphorane give predominantly the (E) enol-lactone in all examples.The influence of alkyl substituents on the rates of the reactions and the product ratios in both the succinic and glutaric anhydride series is discussed.
