Check Digit Verification of cas no

The CAS Registry Mumber 75508-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,0 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75508-98:
(7*7)+(6*5)+(5*5)+(4*0)+(3*8)+(2*9)+(1*8)=154
154 % 10 = 4
So 75508-98-4 is a valid CAS Registry Number.
