121020-53-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121020-53-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,2 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121020-53:
(8*1)+(7*2)+(6*1)+(5*0)+(4*2)+(3*0)+(2*5)+(1*3)=49
49 % 10 = 9
So 121020-53-9 is a valid CAS Registry Number.

Solid-liquid phase transfer catalytic synthesis VII: The synthesis of α-substituted-2-pyridylmethylamine via the alkylation of benzaldehyde imine
Wang,Mi,Jiang
, p. 265 - 269 (2007/10/02)
The anion derived from the benzaldehyde imine 2 reacts with alkyl halide to form alkylated products 3; Hydrolysis of 3 gives α-alkyl-2 pyridylmethylamine in 34-53% overall yield.
