54554-78-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54554-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,5 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54554-78:
(7*5)+(6*4)+(5*5)+(4*5)+(3*4)+(2*7)+(1*8)=138
138 % 10 = 8
So 54554-78-8 is a valid CAS Registry Number.

Adenine intermediate pyrimidine-azo compound and preparation method thereof

-

Paragraph 0027; 0028; 0029, (2017/07/14)

The invention relates to an adenine intermediate pyrimidine-azo compound and a preparation method thereof. The preparation method comprises the following steps of: 1) dissolving primary amine in mixed-acid solution, dripping sodium nitrite solution to prepare diazonium salt shown in a formula (3), adding malononitrile for dissolving, and dripping alkaline solution to regulate a pH value of reaction solution and generate coupling reaction, thereby obtaining an intermediate pyrimidine-azo compound (4); 2) adding the intermediate pyrimidine-azo compound (4) prepared in the step 1) into formamide, introducing liquid ammonia, and heating to carry out high-temperature condensation and cyclization reaction, thereby obtaining an adenine intermediate pyrimidine-azo compound (5), wherein a series of derivatives of the adenine intermediate pyrimidine-azo compound can be prepared by selecting different primary amines. The adenine intermediate pyrimidine-azo compound and the preparation method have the advantages that water is used as a solvent in the step 1), and the solvent used in the step 2) can be repeatedly used, so that the 'three wastes' are fewer, and the environment-friendly effect is achieved; and the cost is low, so that the industrialization is easy and the economic benefit is obvious.
