Check Digit Verification of cas no

The CAS Registry Mumber 70499-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,4,9 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70499-31:
(7*7)+(6*0)+(5*4)+(4*9)+(3*9)+(2*3)+(1*1)=139
139 % 10 = 9
So 70499-31-9 is a valid CAS Registry Number.
