Check Digit Verification of cas no

The CAS Registry Mumber 221622-80-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,2 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 221622-80:
(8*2)+(7*2)+(6*1)+(5*6)+(4*2)+(3*2)+(2*8)+(1*0)=96
96 % 10 = 6
So 221622-80-6 is a valid CAS Registry Number.
