Check Digit Verification of cas no
The CAS Registry Mumber 5022-68-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,2 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5022-68:
(6*5)+(5*0)+(4*2)+(3*2)+(2*6)+(1*8)=64
64 % 10 = 4
So 5022-68-4 is a valid CAS Registry Number.

The synthesis of 5,7-dimethyl-1,2,4-triazolo[1,5a(14C)] pyrimidine-2-carbaldehyde from [14C]aminoguanidine: A key intermediate for the radiochemical GMP synthesis of a drug candidate

Hydrazination of barium [14C]cyanamide and hydrazinolysis of S-methylisothio[14C]urea were compared for their ability to efficiently prepare [14C]aminoguanidine bicarbonate. [ 14C]Aminoguanidine bicarbonate was converted in three steps to 5, 7-dimethyl-1,2,4-triazolo[1,5a(14C)]pyrimidine-2-carbaldehyde, a key radiochemical GMP starting material. Copyright
