Check Digit Verification of cas no

The CAS Registry Mumber 173379-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,7 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 173379-31:
(8*1)+(7*7)+(6*3)+(5*3)+(4*7)+(3*9)+(2*3)+(1*1)=152
152 % 10 = 2
So 173379-31-2 is a valid CAS Registry Number.
