(4-Methoxyphenyl)methyl (2S,5R,6R)-3,3-dimethyl-4,7-dioxo-6-[(2-phenylacetyl)amino]-4lambda4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylate's ester nature and the presence of a phenylacetyl group may contribute to its potential therapeutic effects, which need to be experimentally determined for various medical applications.
Check Digit Verification of cas no
The CAS Registry Mumber 53956-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,5 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53956-74:
(7*5)+(6*3)+(5*9)+(4*5)+(3*6)+(2*7)+(1*4)=154
154 % 10 = 4
So 53956-74-4 is a valid CAS Registry Number.

Preparation of 7-phenylacetamide-3-chloromethyl-cephalosporanic acid p-methoxybenzyl ester
-
Paragraph 0024; 0025, (2017/09/02)
The invention belongs to the field of synthesis of cephalosporin drug intermediates and disclosesa preparation method of 7-phenylacetamide-3-chloromethyl-cephalosporanic acid p-methoxybenzyl ester (short for GCLE). According to the method, penicillin G potassium salt taken as an initial raw material reacts with 4-methoxybenzylchloride firstly, penicillin sulfoxide ester is prepared through oxidation with peracetic acid and reacts with 2-mercaptobenzothiazole firstly, then a product reacts with benzene sulfinic acid, a ring opening product is obtained and reacts with chlorine, sodium methoxide is used for ring closing under the action of a methanol solvent, and 7-phenylacetamide-3-chloromethyl-cephalosporanic acid p-methoxybenzyl ester is obtained. The solvent is simple and easy to recover, reaction conditions are mild, operation is simple and convenient, and industrial production is easy.
