220580-60-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220580-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,8 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220580-60:
(8*2)+(7*2)+(6*0)+(5*5)+(4*8)+(3*0)+(2*6)+(1*0)=99
99 % 10 = 9
So 220580-60-9 is a valid CAS Registry Number.
