Check Digit Verification of cas no
The CAS Registry Mumber 220904-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,0 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 220904-98:
(8*2)+(7*2)+(6*0)+(5*9)+(4*0)+(3*4)+(2*9)+(1*8)=113
113 % 10 = 3
So 220904-98-3 is a valid CAS Registry Number.
