Check Digit Verification of cas no

The CAS Registry Mumber 1428333-35-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,3 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1428333-35:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*3)+(3*3)+(2*3)+(1*5)=150
150 % 10 = 0
So 1428333-35-0 is a valid CAS Registry Number.

Electrochemical C-H amination: Synthesis of aromatic primary amines via N -arylpyridinium ions

Morofuji, Tatsuya,Shimizu, Akihiro,Yoshida, Jun-Ichi

, p. 5000 - 5003 (2013)

We have developed a new method for C-H amination of aromatic compounds based on electrochemical oxidation of aromatic compounds in the presence of pyridine followed by the reaction of the resulting N-arylpyridinium ions with an alkylamine. This new transformation serves as a powerful method for synthesizing aromatic primary amines from aromatic compounds without using metal catalysts and harsh chemical reagents. High chemoselectivity of the present method is demonstrated by C-H amination of aromatic compounds bearing a nitro group to give a key intermediate for the synthesis of VLA-4 antagonist.
