Check Digit Verification of cas no

The CAS Registry Mumber 13039-94-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,3 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 13039-94:
(7*1)+(6*3)+(5*0)+(4*3)+(3*9)+(2*9)+(1*4)=86
86 % 10 = 6
So 13039-94-6 is a valid CAS Registry Number.
