Check Digit Verification of cas no

The CAS Registry Mumber 130649-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130649-71:
(8*1)+(7*3)+(6*0)+(5*6)+(4*4)+(3*9)+(2*7)+(1*1)=117
117 % 10 = 7
So 130649-71-7 is a valid CAS Registry Number.
