116221-91-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116221-91-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,2,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116221-91:
(8*1)+(7*1)+(6*6)+(5*2)+(4*2)+(3*1)+(2*9)+(1*1)=91
91 % 10 = 1
So 116221-91-1 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.
