Check Digit Verification of cas no

The CAS Registry Mumber 33985-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,8 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33985-51:
(7*3)+(6*3)+(5*9)+(4*8)+(3*5)+(2*5)+(1*1)=142
142 % 10 = 2
So 33985-51-2 is a valid CAS Registry Number.
