Check Digit Verification of cas no

The CAS Registry Mumber 221659-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,6,5 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 221659-33:
(8*2)+(7*2)+(6*1)+(5*6)+(4*5)+(3*9)+(2*3)+(1*3)=122
122 % 10 = 2
So 221659-33-2 is a valid CAS Registry Number.
