Check Digit Verification of cas no
The CAS Registry Mumber 21742-00-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,4 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21742-00:
(7*2)+(6*1)+(5*7)+(4*4)+(3*2)+(2*0)+(1*0)=77
77 % 10 = 7
So 21742-00-7 is a valid CAS Registry Number.

, (2017/06/24)
The invention provides a preparation method of 2-methyl-5-aminotrifluorotoluene. The method comprises the following steps: reducing 2-trifluoromethylbenzaldehyde, serving as a raw material, with sodium borohydride to obtain 2-trifluoromethyl benzyl alcohol; performing chlorination by sulfoxide chloride to obtain 2-trifluoromethyl benzyl chloride; nitrifying to obtain 2-chloromethyl-5-nitryltrifluorotoluene; lastly, performing hydrogenation reduction to obtain a target product, namely, 2-methyl-5-aminotrifluorotoluene. The method has the advantages of easiness in operation, high product yield, low cost and easiness in industrialization. The chemical formula of the 2-methyl-5-aminotrifluorotoluene is shown in the description.
