220398-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220398-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,3,9 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220398-58:
(8*2)+(7*2)+(6*0)+(5*3)+(4*9)+(3*8)+(2*5)+(1*8)=123
123 % 10 = 3
So 220398-58-3 is a valid CAS Registry Number.
