89969-65-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89969-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 89969-65:
(7*8)+(6*9)+(5*9)+(4*6)+(3*9)+(2*6)+(1*5)=223
223 % 10 = 3
So 89969-65-3 is a valid CAS Registry Number.

Synthesis and some reactions of 1-α-cyanoalkyl(aralkyl)-2-pyrazolines
Vorozhtov,Golubeva
, p. 1307 - 1313 (2007/10/03)
1-α-Cyanoalkyl(aralkyl)-2-pyrazolines were obtained by the reaction of 1-alkylidene(arylidene)-2-pyrazolinium tetrafluoroborates with metal cyanides. Reduction of the products led to substituted β-aminoalkyl-2- pyrazolines. Hydrolysis of the nitrile group
