Check Digit Verification of cas no

The CAS Registry Mumber 109548-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,4 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109548-64:
(8*1)+(7*0)+(6*9)+(5*5)+(4*4)+(3*8)+(2*6)+(1*4)=143
143 % 10 = 3
So 109548-64-3 is a valid CAS Registry Number.
