Check Digit Verification of cas no

The CAS Registry Mumber 99648-60-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,6,4 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99648-60:
(7*9)+(6*9)+(5*6)+(4*4)+(3*8)+(2*6)+(1*0)=199
199 % 10 = 9
So 99648-60-9 is a valid CAS Registry Number.
