Check Digit Verification of cas no

The CAS Registry Mumber 189105-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,0 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 189105-47:
(8*1)+(7*8)+(6*9)+(5*1)+(4*0)+(3*5)+(2*4)+(1*7)=153
153 % 10 = 3
So 189105-47-3 is a valid CAS Registry Number.
