90840-07-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90840-07-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90840-07:
(7*9)+(6*0)+(5*8)+(4*4)+(3*0)+(2*0)+(1*7)=126
126 % 10 = 6
So 90840-07-6 is a valid CAS Registry Number.

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
