Check Digit Verification of cas no
The CAS Registry Mumber 83494-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,9 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83494-28:
(7*8)+(6*3)+(5*4)+(4*9)+(3*4)+(2*2)+(1*8)=154
154 % 10 = 4
So 83494-28-4 is a valid CAS Registry Number.

Paragraph 0028-0029; 0031-0032; 0034-0035; 0037-0038; 0040, (2020/09/21)
The invention discloses a preparation method of a flomoxef 7-site side chain, which comprises the following steps: dissolving methyl mercaptoacetate, as an initial raw material, in a lower alcohol, introducing monochlorodifluoromethane gas under the catalysis of an organic strong base, washing the reaction product with water, carrying out aftertreatment purification, and carrying out hydrolysis reaction with alkali to form a salt, thereby obtaining the flomoxef 7-site side chain. All the materials used in the method are cheap and easy to obtain, and the cost is low; reaction conditions are mild, energy consumption is low, industrial production is facilitated, and pollution is small; the purity of the obtained product is up to 99%, and the product is good in stability and easy to store.
