Check Digit Verification of cas no

The CAS Registry Mumber 391257-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,1,2,5 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 391257-75:
(8*3)+(7*9)+(6*1)+(5*2)+(4*5)+(3*7)+(2*7)+(1*5)=163
163 % 10 = 3
So 391257-75-3 is a valid CAS Registry Number.
