Check Digit Verification of cas no

The CAS Registry Mumber 152903-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,9,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 152903-48:
(8*1)+(7*5)+(6*2)+(5*9)+(4*0)+(3*3)+(2*4)+(1*8)=125
125 % 10 = 5
So 152903-48-5 is a valid CAS Registry Number.
