Check Digit Verification of cas no
The CAS Registry Mumber 87215-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,1 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87215-91:
(7*8)+(6*7)+(5*2)+(4*1)+(3*5)+(2*9)+(1*1)=146
146 % 10 = 6
So 87215-91-6 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
