Check Digit Verification of cas no

The CAS Registry Mumber 1131-52-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1131-52:
(6*1)+(5*1)+(4*3)+(3*1)+(2*5)+(1*2)=38
38 % 10 = 8
So 1131-52-8 is a valid CAS Registry Number.

New synthesis process for 3-methoxyl-4-ethoxybenzonitrile

-

Paragraph 0024; 0028; 0031; 0034, (2017/09/01)

The invention discloses a new synthesis process for 3-methoxyl-4-ethoxybenzonitrile, and relates to the technical field of organic synthesis. The new synthesis process for the 3-methoxyl-4-ethoxybenzonitrile comprises the following steps: taking ethyl vanillin as a raw material, taking N,N-dimethylformamide as a solvent, reacting the raw material and the solvent with potassium carbonate at first to form potassium salt, and reacting the obtained potassium salt with methyl iodide to obtain 3-methoxyl-4-ethoxy-benzaldehyde as an intermediate; adding hydroxylamine hydrochloride in a formic acid solution of the 3-methoxyl-4-ethoxy-benzaldehyde as the intermediate, heating and dehydrating, and carrying out desolventizing and recrystallization to obtain the high-purity 3-methoxyl-4-ethoxybenzonitrile finished product. The ethyl vanillin which is low in cost and is easily obtained as the raw material, aftertreatment operation is simple, and after being recycled, the N,N-dimethylformamide as the solvent can be directly used for other items; the 3-methoxyl-4-ethoxy-benzaldehyde as the intermediate are used for next reaction when not purified, so that purification cost is saved, and yield loss is avoided; and moreover, solid wastes are not produced in the whole process, and the total yield reaches 93.8%.
