Check Digit Verification of cas no

The CAS Registry Mumber 136430-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,4,3 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136430-43:
(8*1)+(7*3)+(6*6)+(5*4)+(4*3)+(3*0)+(2*4)+(1*3)=108
108 % 10 = 8
So 136430-43-8 is a valid CAS Registry Number.
