Check Digit Verification of cas no

The CAS Registry Mumber 222055-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,0,5 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 222055-44:
(8*2)+(7*2)+(6*2)+(5*0)+(4*5)+(3*5)+(2*4)+(1*4)=89
89 % 10 = 9
So 222055-44-9 is a valid CAS Registry Number.
