Check Digit Verification of cas no
The CAS Registry Mumber 452-07-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 452-07:
(5*4)+(4*5)+(3*2)+(2*0)+(1*7)=53
53 % 10 = 3
So 452-07-3 is a valid CAS Registry Number.

2. 4 - difluorobenzene methylamine synthetic method
-
Paragraph 0036-0040, (2017/10/22)
The invention relates to the fields of medicine and agrochemicals, and concretely relates to a synthetic method of an intermediate 2,4-difluorobenzene methylamine. The synthetic method comprises the following steps: 1) m-difluorobenzene, a halogenating agent and paraformaldehyde are reacted under effect of a catalyst to prepare 2,4-difluoro benzyl halide; 2)the prepared 2,4-difluoro benzyl halide and urotropine are reacted to prepare a quaternary ammonium salt compound IV; 3)the prepared quaternary ammonium salt compound is hydrolyzed by concentrated hydrochloric acid to obtain 2,4-difluorobenzene methylamine. The method has the advantages of low cost of the prepared 2,4-difluorobenzene methylamine, convenient operation and high security coefficient, and is suitable for industrial production.
