Check Digit Verification of cas no

The CAS Registry Mumber 134641-06-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,4 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134641-06:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*1)+(2*0)+(1*6)=108
108 % 10 = 8
So 134641-06-8 is a valid CAS Registry Number.
