Check Digit Verification of cas no

The CAS Registry Mumber 134643-05-3 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 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134643-05:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*3)+(2*0)+(1*5)=113
113 % 10 = 3
So 134643-05-3 is a valid CAS Registry Number.
