Check Digit Verification of cas no

The CAS Registry Mumber 130779-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,7,7 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130779-67:
(8*1)+(7*3)+(6*0)+(5*7)+(4*7)+(3*9)+(2*6)+(1*7)=138
138 % 10 = 8
So 130779-67-8 is a valid CAS Registry Number.
