67751-02-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67751-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,7,5 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 67751-02:
(7*6)+(6*7)+(5*7)+(4*5)+(3*1)+(2*0)+(1*2)=144
144 % 10 = 4
So 67751-02-4 is a valid CAS Registry Number.

Synthesis of pyridine derivatives using aza Diels-Alder methodology
Stanforth, Stephen P.,Tarbit, Brian,Watson, Michael D.
, p. 6015 - 6017 (2002)
Amidrazone 1 reacted with the unsymmetrical tricarbonyls 2a, 2c and 2d giving triazines 3a, 3c and 3d, respectively. These triazines were converted into their corresponding pyridine derivatives 6a, 6c and 6d in aza Diels-Alder reactions with 2,5-norbornad
