Check Digit Verification of cas no

The CAS Registry Mumber 85142-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,4 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85142-56:
(7*8)+(6*5)+(5*1)+(4*4)+(3*2)+(2*5)+(1*6)=129
129 % 10 = 9
So 85142-56-9 is a valid CAS Registry Number.
