521098-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 521098-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,1,0,9 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 521098-75:
(8*5)+(7*2)+(6*1)+(5*0)+(4*9)+(3*8)+(2*7)+(1*5)=139
139 % 10 = 9
So 521098-75-9 is a valid CAS Registry Number.

N1-(5-Aryl-1,3,4-oxadiazolo-2-yl)-ureas on cyclocondensation with CS2/KOH afford 2-aryl-1,3,4-oxadiazole[3,2-a]-s-triazine-5,7-(6H) dithione nucleobase which on glycosylation with different sugars gives nucleoside analogues.
