Check Digit Verification of cas no
The CAS Registry Mumber 1269293-48-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,2,9 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1269293-48:
(9*1)+(8*2)+(7*6)+(6*9)+(5*2)+(4*9)+(3*3)+(2*4)+(1*8)=192
192 % 10 = 2
So 1269293-48-2 is a valid CAS Registry Number.

, (2020/12/30)
The invention discloses a synthesis method of 5-bromine-1-methyl-1H-pyrazole-3-amine. The method comprises the steps of condensing diethyl butynedioate serving as a raw material with methylhydrazine to obtain 5-hydroxyl-1-methyl-1H-pyrazole-3-carboxylic acid ethyl ester, and reacting the 5-hydroxyl-1-methyl-1H-pyrazole-3-carboxylic acid ethyl ester with phosphorus oxybromide to obtain 5-bromine-1-methyl-1H-pyrazole-3-carboxylic acid ethyl ester; hydrolyzing in a sodium hydroxide alcohol solution to obtain 5-bromine-1-methyl-1H-pyrazole-3-carboxylic acid, reacting the 5-bromine-1-methyl-1H-pyrazole-3-carboxylic acid with dimethyl azide phosphate and tert-butyl alcohol to obtain tert-butyl (5-bromine-1-methyl-1H-pyrazole-3-yl) carbamate, and hydrolyzing in trifluoroacetic acid to obtain the5-bromine-1-methyl-1H-pyrazole-3-amine. The method has the advantages of simple synthesis route, reasonable process selection, low raw material cost, simple and easily available raw materials, convenient operation and post-treatment, and no use of highly toxic reagents, and overcomes the defects of expensive and unavailable raw materials, unsafe operation, difficult amplification and the like in the existing synthesis process.
