Check Digit Verification of cas no

The CAS Registry Mumber 128156-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,5 and 6 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 128156-33:
(8*1)+(7*2)+(6*8)+(5*1)+(4*5)+(3*6)+(2*3)+(1*3)=122
122 % 10 = 2
So 128156-33-2 is a valid CAS Registry Number.
