220066-69-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220066-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,6 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220066-69:
(8*2)+(7*2)+(6*0)+(5*0)+(4*6)+(3*6)+(2*6)+(1*9)=93
93 % 10 = 3
So 220066-69-3 is a valid CAS Registry Number.
