Check Digit Verification of cas no

The CAS Registry Mumber 220826-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,2 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220826-33:
(8*2)+(7*2)+(6*0)+(5*8)+(4*2)+(3*6)+(2*3)+(1*3)=105
105 % 10 = 5
So 220826-33-5 is a valid CAS Registry Number.
