Check Digit Verification of cas no

The CAS Registry Mumber 2741-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2741-57:
(6*2)+(5*7)+(4*4)+(3*1)+(2*5)+(1*7)=83
83 % 10 = 3
So 2741-57-3 is a valid CAS Registry Number.

A O-trifluoro methyl process for the preparation of formaldehyde

-

Paragraph 0036; 0037; 0038, (2017/02/23)

The invention discloses a method for preparing o-trifluoromethyl benzaldehyde. The method for preparing the o-trifluoromethyl benzaldehyde, disclosed by the invention, comprises the following steps: in the presence of a catalyst, carrying out hydrolysis reaction on a mixture of o-trifluoromethyl methylbenzene bichloride, o-trifluoromethyl chloro-fluoro-methylbenzene and o-trifluoromethyl methylbenzene difluoride and water at the temperature of 80-150 DEG C to obtain, wherein the mass of the catalyst accounts for 0.01-10% of the mass of the mixture. The method disclosed by the invention is cheap and easily available in raw materials, low in cost, little in wastewater, low in energy consumption and simple in operation and can be suitable for industrial production. The structural formula of the o-trifluoromethyl benzaldehyde is shown in the specification.
