66940-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66940-97-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,4 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66940-97:
(7*6)+(6*6)+(5*9)+(4*4)+(3*0)+(2*9)+(1*7)=164
164 % 10 = 4
So 66940-97-4 is a valid CAS Registry Number.

Methods for the synthesis of 6-arylamino-5,5-diethyl-3H,5H-pyrimidine-2,4-diones from the corresponding 6-thioxo and 6-amino derivatives were developed.The isomeric 2-arylamino-5,5-diethyl-1H,5H-pyrimidine-4,6-diones were obtained by the reaction of 2-mer
