Check Digit Verification of cas no

The CAS Registry Mumber 112671-87-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,6,7 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112671-87:
(8*1)+(7*1)+(6*2)+(5*6)+(4*7)+(3*1)+(2*8)+(1*7)=111
111 % 10 = 1
So 112671-87-1 is a valid CAS Registry Number.

Synthesis method of alpha-acylamino ketone compound

-

Paragraph 0027-0029; 0030-0032; 0100, (2020/12/08)

The invention discloses a synthesis method of an alpha-acylamino ketone compound, and belongs to the technical field of organic synthesis. The preparation method comprises the following steps: mixingan alkenyl azide compound 1, a carboxylic acid compound 2 and an organic solvent, and heating to react to obtain the alpha-acylamino ketone compound 3. Compared with the prior art, the method has thefollowing advantages: (1) the synthesis process is simple and efficient, no catalyst is needed in the whole process, and the alpha-acylamino ketone compound can be obtained with high yield by dissolving the alkenyl azide compound and the carboxylic acid compound in the solvent and stirring; (2) raw materials are cheap and easy to obtain, reaction conditions are mild, and operation is simple; (3) the substrate is wide in application range and can be used for modifying drug molecules; and (4) the atom economy is high, and the requirements of green chemistry are met.
