Check Digit Verification of cas no

The CAS Registry Mumber 83221-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,2 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83221-69:
(7*8)+(6*3)+(5*2)+(4*2)+(3*1)+(2*6)+(1*9)=116
116 % 10 = 6
So 83221-69-6 is a valid CAS Registry Number.
