Check Digit Verification of cas no

The CAS Registry Mumber 130685-72-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,8 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 130685-72:
(8*1)+(7*3)+(6*0)+(5*6)+(4*8)+(3*5)+(2*7)+(1*2)=122
122 % 10 = 2
So 130685-72-2 is a valid CAS Registry Number.
