Check Digit Verification of cas no

The CAS Registry Mumber 221651-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,5 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221651-80:
(8*2)+(7*2)+(6*1)+(5*6)+(4*5)+(3*1)+(2*8)+(1*0)=105
105 % 10 = 5
So 221651-80-5 is a valid CAS Registry Number.
