Check Digit Verification of cas no

The CAS Registry Mumber 1248827-74-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,8,2 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1248827-74:
(9*1)+(8*2)+(7*4)+(6*8)+(5*8)+(4*2)+(3*7)+(2*7)+(1*4)=188
188 % 10 = 8
So 1248827-74-8 is a valid CAS Registry Number.
