Check Digit Verification of cas no
The CAS Registry Mumber 220223-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,2 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220223-28:
(8*2)+(7*2)+(6*0)+(5*2)+(4*2)+(3*3)+(2*2)+(1*8)=69
69 % 10 = 9
So 220223-28-9 is a valid CAS Registry Number.
