Check Digit Verification of cas no

The CAS Registry Mumber 544669-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,4,6,6 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 544669-64:
(8*5)+(7*4)+(6*4)+(5*6)+(4*6)+(3*9)+(2*6)+(1*4)=189
189 % 10 = 9
So 544669-64-9 is a valid CAS Registry Number.

A novel and facile synthesis of 3,4-diacyl-2H-pyran-2-ones. New C[Formula presented]C bond formation

Kotali, Antigoni,Nasiopoulou, Despina A.,Harris, Philip A.

, p. 3488 - 3490 (2016)

The two-step synthesis of 3,4-diacyl-2H-pyran-2-ones was achieved in good yields from dehydroacetic acid via transformation of the hydroxyl group into an acyl group (TROHIA). This transformation which was earlier explored using the benzene nucleus of seve

Synthesis of novel dehydroacetic acid N-aroylhydrazone-derived boron heterocycles

Kotali, Antigoni,Dimoulaki, Fani,Kotali, Elvira,Maniadaki, Anna,Harris, Philip A.,Rózycka-Soko?owska, Ewa,Ba?czewski, Piotr,Joule, John A.

, p. 7245 - 7249 (2015/08/24)

Abstract The synthesis of new boron heterocycles is reported via the reaction of dehydroacetic acid N-aroylhydrazones with boron acetate. The procedure involves formation of new zwitterionic, tetrahedral boron structures.
