Check Digit Verification of cas no

The CAS Registry Mumber 861643-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,6,4 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 861643-06:
(8*8)+(7*6)+(6*1)+(5*6)+(4*4)+(3*3)+(2*0)+(1*6)=173
173 % 10 = 3
So 861643-06-3 is a valid CAS Registry Number.
