132056-88-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 132056-88-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,0,5 and 6 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 132056-88:
(8*1)+(7*3)+(6*2)+(5*0)+(4*5)+(3*6)+(2*8)+(1*8)=103
103 % 10 = 3
So 132056-88-3 is a valid CAS Registry Number.

A facile and practical synthesis of 9-Methyl-3-(1H-tetrazol-5-yl)-4H-pyrido[1,2-a]pyrimidin-4-one

Sano,Ishihara,Yoshihara,Sumino,Nawa

, p. 683 - 685 (1995)

A facile and practical synthesis of 9-methyl-3-(1H-tetrazol-5-yl)-4H-pyrido[1,2-a]pyrimidin-4-one (4), the potassium salt of which is used clinically as an anti-asthma agent, is described. Treatment of a key intermediate (6b), prepared from 2-amino-3-methylpyridine (1) and 2-ethoxymethylene-1,3-propanedinitrile, with sodium azide in N,N-dimethylformamide gave predominantly the cyanotetrazole (7a), while in acetic acid it gave exclusively the iminotetrazole (7b), which was easily converted into 4 by acid hydrolysis. A one-pot process starting from 6b to give 4, avoiding the use of explosive aluminum azide, was established.

Process for producing 3-tetrazolyl pyrido[1,2-a]pyrimidine derivatives

-

, (2008/06/13)

3-Tetrazolylpyrido[1,2-a]pyrimidin-4-one derivatives useful as an antiallergy agent are produced by reacting a cyano derivative of pyrido[1,2-a]pyrimidin-4-one compound with (i) hydrazoic acid, followed by hydrolysis, or with (ii) a salt of hydrazoic acid
