6278-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6278-77-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6278-77:
(6*6)+(5*2)+(4*7)+(3*8)+(2*7)+(1*7)=119
119 % 10 = 9
So 6278-77-9 is a valid CAS Registry Number.

A series of N-substituted 8-aminoxanthines (=8-amino-3,7(or 3,9)-dihydro-1H-purine-2,6-diones) 8-16 and 34-37 were synthesized from the corresponding 8-nitroxanthines 1-7, 30-33, and 8-(phenylazo)xanthines 17 and 18 by catalytic reduction. Another approac
