Check Digit Verification of cas no

The CAS Registry Mumber 1064157-08-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,4,1,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1064157-08:
(9*1)+(8*0)+(7*6)+(6*4)+(5*1)+(4*5)+(3*7)+(2*0)+(1*8)=129
129 % 10 = 9
So 1064157-08-9 is a valid CAS Registry Number.
