Check Digit Verification of cas no

The CAS Registry Mumber 201989-33-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,9,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 201989-33:
(8*2)+(7*0)+(6*1)+(5*9)+(4*8)+(3*9)+(2*3)+(1*3)=135
135 % 10 = 5
So 201989-33-5 is a valid CAS Registry Number.
