Check Digit Verification of cas no

The CAS Registry Mumber 134440-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,4,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134440-87:
(8*1)+(7*3)+(6*4)+(5*4)+(4*4)+(3*0)+(2*8)+(1*7)=112
112 % 10 = 2
So 134440-87-2 is a valid CAS Registry Number.
