91561-14-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91561-14-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,5,6 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91561-14:
(7*9)+(6*1)+(5*5)+(4*6)+(3*1)+(2*1)+(1*4)=127
127 % 10 = 7
So 91561-14-7 is a valid CAS Registry Number.

Method for synthesizing alecensa hydrochloride intermediate 2-(4-ethyl-3-iodophenyl)-2-methylpropanoic acid

-

Paragraph 0054; 0055; 0056; 0057; 0065-0068; 0076-0079, (2019/04/02)

The invention discloses a method for synthesizing an alecensa hydrochloride intermediate 2-(4-ethyl-3-iodophenyl)-2-methylpropanoic acid. The method is characterized by comprising steps of carrying out Friedel-Crafts reaction on ethylbenzene and 3-halogen-2-methyl-1-propylene to obtain 1-halogn-2-(4-ethyl phenyl)-2-methylpropane; carrying out reaction on the 1-halogn-2-(4-ethyl phenyl)-2-methylpropane and magnesium to obtain 2-(4-ethyl phenyl)-2-methyl propyl magnesium halide; carrying out reaction on the 2-(4-ethyl phenyl)-2-methyl propyl magnesium halide and oxygen to obtain 2-(4-ethyl phenyl)-2-methyl-1-propyl alcohol; oxidizing the 2-(4-ethyl phenyl)-2-methyl-1-propyl alcohol, sodium hypochlorite and sodium chlorite by the aid of 2,2,6,6-tetramethyl piperidine oxide to obtain 2-(4-ethyl phenyl)-2-methylpropanoic acid; carrying out reaction on the 2-(4-ethyl phenyl)-2-methylpropanoic acid and iodine in the presence of oxidizing agents under acidic conditions to obtain the alecensa hydrochloride intermediate. 2-(4-ethyl-3-iodophenyl)-2-methylpropanoic acid. The 2,2,6,6-tetramethyl piperidine oxide is used as a catalyst. The method has the advantages that the method is easy and convenient to operate, high in yield, low in cost and little in pollution, raw materials for the alecensa hydrochloride intermediate 2-(4-ethyl-3-iodophenyl)-2-methylpropanoic acid are inexpensive and are easily available, and industrial production can be facilitated.
