Check Digit Verification of cas no

The CAS Registry Mumber 518070-29-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,8,0,7 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 518070-29:
(8*5)+(7*1)+(6*8)+(5*0)+(4*7)+(3*0)+(2*2)+(1*9)=136
136 % 10 = 6
So 518070-29-6 is a valid CAS Registry Number.
