Check Digit Verification of cas no

The CAS Registry Mumber 220222-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,2,2 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220222-91:
(8*2)+(7*2)+(6*0)+(5*2)+(4*2)+(3*2)+(2*9)+(1*1)=73
73 % 10 = 3
So 220222-91-3 is a valid CAS Registry Number.
