Check Digit Verification of cas no

The CAS Registry Mumber 90609-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,0 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90609-99:
(7*9)+(6*0)+(5*6)+(4*0)+(3*9)+(2*9)+(1*9)=147
147 % 10 = 7
So 90609-99-7 is a valid CAS Registry Number.
