Check Digit Verification of cas no

The CAS Registry Mumber 38540-31-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,4 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38540-31:
(7*3)+(6*8)+(5*5)+(4*4)+(3*0)+(2*3)+(1*1)=117
117 % 10 = 7
So 38540-31-7 is a valid CAS Registry Number.
