Check Digit Verification of cas no
The CAS Registry Mumber 3663-24-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3663-24:
(6*3)+(5*6)+(4*6)+(3*3)+(2*2)+(1*4)=89
89 % 10 = 9
So 3663-24-9 is a valid CAS Registry Number.

-
, (2016/12/01)
The present invention discloses a 5-n-butyl-1H-benzotriazole synthesis process, which comprises: adding concentrated sulfuric acid to acetic anhydride in a dropwise manner, and adding 4-n-butyl aniline in a dropwise manner to prepare 4-n-butyl acetanilide; adding a mixed acid solution comprising 65% concentrated nitric acid and acetic anhydride to the 4-n-butyl acetanilide in a dropwise manner to synthesize 4-n-butyl-2-nitro acetanilide; synthesizing 4-n-butyl-2-nitroaniline by using the 4-n-butyl-2-nitro acetanilide, 95% ethanol and 40% sodium hydroxide as raw materials; under the effect of a catalyst, using the 4-n-butyl-2-nitroaniline and dehydrated alcohol and sequentially using nitrogen and hydrogen to convert under a closed condition to prepare 4-n-butyl-o-phenylenediamine; and adding the 4-n-butyl-o-phenylenediamine, water and sodium nitrite to an autoclave to synthesize the 5-n-butyl-1H-benzotriazole. According to the present invention, the process equipment is simple, and the product yield is high.
