Check Digit Verification of cas no

The CAS Registry Mumber 1352448-55-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,4,4 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1352448-55:
(9*1)+(8*3)+(7*5)+(6*2)+(5*4)+(4*4)+(3*8)+(2*5)+(1*5)=155
155 % 10 = 5
So 1352448-55-5 is a valid CAS Registry Number.
