1165-48-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1165-48-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1165-48:
(6*1)+(5*1)+(4*6)+(3*5)+(2*4)+(1*8)=66
66 % 10 = 6
So 1165-48-6 is a valid CAS Registry Number.

Preparation method and application of dimenephrine hydrochloride intermediate 7-methoxy-3-methyl flavone

-

Paragraph 0029-0033, (2021/04/10)

The invention provides a preparation method of a dimenephrine hydrochloride intermediate 7-methoxy 3-methyl flavone, which comprises the following steps: carrying out cyclization reaction on a compound IIa: 2, 4-dihydroxy propiophenone and a compound IIb: benzoyl chloride under the action of sodium benzoate to obtain a compound III: 7-methoxy-3-methyl flavone; according to the preparation method of the intermediate 7-methoxy-3-methyl flavone, provided by the invention, methylated 2, 4-dihydroxy propiophenone and benzoyl chloride are synthesized by adopting a one-step method, so that the prepared intermediate 7-methoxy-3-methyl flavone is high in purity, few in process impurities, high in yield and simple to operate; the invention further provides application of the 7-methoxy 3-methyl flavone in preparation of the dimenephrine hydrochloride, the yield of the dimenephrine hydrochloride is higher, and the specific preparation operation process is simple.
