Check Digit Verification of cas no

The CAS Registry Mumber 33981-31-6 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 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 33981-31:
(7*3)+(6*3)+(5*9)+(4*8)+(3*1)+(2*3)+(1*1)=126
126 % 10 = 6
So 33981-31-6 is a valid CAS Registry Number.
