Check Digit Verification of cas no

The CAS Registry Mumber 83918-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,1 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83918-31:
(7*8)+(6*3)+(5*9)+(4*1)+(3*8)+(2*3)+(1*1)=154
154 % 10 = 4
So 83918-31-4 is a valid CAS Registry Number.
