503073-45-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 503073-45-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,0,7 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503073-45:
(8*5)+(7*0)+(6*3)+(5*0)+(4*7)+(3*3)+(2*4)+(1*5)=108
108 % 10 = 8
So 503073-45-8 is a valid CAS Registry Number.

Convenient synthesis of substituted α-methylene-δ- valerolactones in aqueous medium using Baylis-Hillman chemistry

Singh, Vijay,Batra, Sanjay

, p. 63 - 72 (2007/10/03)

A mild and convenient synthesis of substituted α-methylene-δ- valerolactones was achieved by SN2 nucleophilic substitution of the acetates of Baylis-Hillman adducts with acetyl acetone followed by one-pot saponification of the ester, reduction

Baylis-Hillman reaction assisted parallel synthesis of 3,5-disubstituted isoxazoles and their in vivo bioevaluation as antithrombotic agents

Batra,Roy,Patra,Bhaduri,Surin,Raghavan,Sharma,Kapoor,Dikshit

, p. 2059 - 2077 (2007/10/03)

The solution-phase parallel synthesis involving reactions of Baylis-Hillman products of 3-substituted-5-isoxazolecarbaldehydes with nucleophiles and their in vivo antithrombotic evaluations are described along with the results of in vitro platelet aggregation inhibition assay of a few compounds. Results of the detailed evaluation of one of the compounds as an inhibitor of platelet aggregation are also presented.
