Check Digit Verification of cas no

The CAS Registry Mumber 155375-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,7 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 155375-53:
(8*1)+(7*5)+(6*5)+(5*3)+(4*7)+(3*5)+(2*5)+(1*3)=144
144 % 10 = 4
So 155375-53-4 is a valid CAS Registry Number.
