73239-22-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 73239-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,2,3 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73239-22:
(7*7)+(6*3)+(5*2)+(4*3)+(3*9)+(2*2)+(1*2)=122
122 % 10 = 2
So 73239-22-2 is a valid CAS Registry Number.

Amidoalkylating properties of 1-(N -acylamino)alkyltriphenylphosphonium salts

Pazdzierniok-Holewa, Agnieszka,Adamek, Jakub,Mazurkiewicz, Roman,Zielinska, Katarzyna

, p. 205 - 212 (2013/07/05)

Easily accessible 1-(N-acylamino)alkyltriphenylphosphonium salts react smoothly with nitrogen, sulfur, phosphorus and oxygen nucleophiles in the presence of (i-Pr)2EtN to give the expected α-amidoalkylation products, usually in good or very good yields. α-Amidoalkylation of dialkyl malonates or acetylacetates requires the application of a much stronger base (DBU) and gives the best results under the influence of microwave irradiation. α-Amidoalkylation of enamines was carried out successfully in the presence of (i-Pr)2EtN in a microwave reactor. 1-(N-Acylamino)alkyltriphenylphosphonium salts can be considered as new, convenient and effective α-amidoalkylation agents.
