Check Digit Verification of cas no

The CAS Registry Mumber 90806-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,0 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90806-95:
(7*9)+(6*0)+(5*8)+(4*0)+(3*6)+(2*9)+(1*5)=144
144 % 10 = 4
So 90806-95-4 is a valid CAS Registry Number.
