Check Digit Verification of cas no

The CAS Registry Mumber 1148-32-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 8 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1148-32:
(6*1)+(5*1)+(4*4)+(3*8)+(2*3)+(1*2)=59
59 % 10 = 9
So 1148-32-9 is a valid CAS Registry Number.
