17667-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17667-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,6 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 17667-55:
(7*1)+(6*7)+(5*6)+(4*6)+(3*7)+(2*5)+(1*5)=139
139 % 10 = 9
So 17667-55-9 is a valid CAS Registry Number.

An efficient green protocol for the preparation of acetoacetamides and application of the methodology to a one-pot synthesis of Biginelli dihydropyrimidines. Expansion of dihydropyrimidine topological chemical space

Gama, Fernando H. S.,De Souza, Rodrigo O. M. A.,Garden, Simon J.

, p. 70915 - 70928 (2015/09/08)

The present study describes the preparation of N-aryl-(15) and N-alkyl-(17) acetoacetamides, in good to excellent yields, using both conventional and microwave heating, by reaction of amine derivatives (14 and 16) with 2,2,6-trimethyl-4H-1,3-dioxin-4-one (TMD, 12) in aqueous medium. The acetoacetamides were used to prepare novel Biginelli dihydropyrimidine derivatives. The introduction of the amino acid derivatives potentially allows for the exploration of new structural complexity and topologically diversifies the chemical space occupied by this versatile chemical scaffold.
