503417-35-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 503417-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,4,1 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 503417-35:
(8*5)+(7*0)+(6*3)+(5*4)+(4*1)+(3*7)+(2*3)+(1*5)=114
114 % 10 = 4
So 503417-35-4 is a valid CAS Registry Number.

Primary 1-Arylcyclopropylamines from aryl cyanides with diethylzinc and titanium alkoxides
Wiedemann, Stefan,Frank, Daniel,Winsel, Harald,De Meijere, Armin
, p. 753 - 755 (2007/10/03)
(Matrix presented) 1-Aryl-substituted primary cyclopropylamines are conveniently prepared from aromatic nitriles and diethylzinc. The yields range from 40 to 56% for donor-substituted (five examples) to 62-82% for non- and acceptor-substituted substrates
