125055-66-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125055-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,0,5 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125055-66:
(8*1)+(7*2)+(6*5)+(5*0)+(4*5)+(3*5)+(2*6)+(1*6)=105
105 % 10 = 5
So 125055-66-5 is a valid CAS Registry Number.

Nitrogen bridgehead compounds. Part 92.* Synthesis of 4-oxo-4H-pyrido[1,2-a]pyriniidine-3-carboxamides, -3-acetamides and their tetrahydro derivatives

Hermecz, Istvan,Vasvari-Debreczy, Lelle,Horvath, Agnes,Sipos, Judit,Balogh, Maria,Podanyi, Benjamin,Kovacs, Katalin

, p. 515 - 528 (2007/10/03)

N-Substituted 4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carboxamides (6-45), -3-acetamides (59-61) and 1,6-dimethyl-4-oxo-1,6,7,8-tetrahydro-4H-pyrido[1,2-a]pyrimidine-3-carhoxamides (63-73) were synthesized in the reaction of amines and mixed anhydrides, prepared from 4-oxo-4H-pyrido[1,2-a]-pyrimidine-3-carboxylic acids (4), -3-acetic acids (58) and 1,6-dimethyl-4-oxo-1,6,7,8-tetrahydropyrido-[1,2-a]pyrimidine-3-carhoxylic acid (62) with methyl or ethyl chloroformate in the presence of triethylamine. Whereas the reaction of 6-methyl-4-oxo-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]pyrimidine-3-acetic acid (53) with 2-phenylethylamines in boilings xylene gave the appropriate N-substituted 3-acetamides (54) and (55), reaction of 6-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-acetic acid (56) with 2-phenylethylamine afforded a pyrrolidin-5-one derivative (57). 3-Acetic hydrazides (47, 48) and (50) were prepared from ethyl 4-oxo-4H-pyrido[1,2-a]pyrimidine-3-acetates (46) and the 6,7,8,9-tetrahydro derivative (49) with hydrazine hydrate. Both 4-oxo-4H-pyrido[1,2-a]pyrimidine-3-acetic hydrazide (47) and 6,7,8,9-tetrahydro-3-acetic hydrazide (50) were converted to 6,7,8,9-tetrahydro-3-acetamides (51, 52) by refluxing them in ethanol over Raney Ni.
