Check Digit Verification of cas no

The CAS Registry Mumber 903906-55-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,9,0 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 903906-55:
(8*9)+(7*0)+(6*3)+(5*9)+(4*0)+(3*6)+(2*5)+(1*5)=168
168 % 10 = 8
So 903906-55-8 is a valid CAS Registry Number.
