Check Digit Verification of cas no
The CAS Registry Mumber 4698-39-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,9 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4698-39:
(6*4)+(5*6)+(4*9)+(3*8)+(2*3)+(1*9)=129
129 % 10 = 9
So 4698-39-9 is a valid CAS Registry Number.

Paragraph 0036; 0047-0049; 0054-0055; 0060-0061; 0066-0067, (2020/12/30)
The invention discloses a synthetic method of doxepin hydrochloride. The synthetic method comprises the following steps: using N, N-dimethyl-3-chloropropylamine as an initial raw material, carrying out Grignard reaction, carrying out addition reaction on the reaction product and 6, 11-dihydrodibenzo [b, e] oxepine-11-ketone, and sequentially carrying out elimination reaction and salifying reactionto synthesize the final product. According to the method, high-purity doxepin hydrochloride can be obtained through four-step synthesis, a substitution reaction is not needed, and the yield of the prepared product is high. Compared with the existing synthesis process, the method has the advantages of few synthesis steps, simple process, short production period, low cost and the like.
