Check Digit Verification of cas no

The CAS Registry Mumber 112885-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,8 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 112885-34:
(8*1)+(7*1)+(6*2)+(5*8)+(4*8)+(3*5)+(2*3)+(1*4)=124
124 % 10 = 4
So 112885-34-4 is a valid CAS Registry Number.
