Check Digit Verification of cas no

The CAS Registry Mumber 220930-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,3 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220930-89:
(8*2)+(7*2)+(6*0)+(5*9)+(4*3)+(3*0)+(2*8)+(1*9)=112
112 % 10 = 2
So 220930-89-2 is a valid CAS Registry Number.
