Check Digit Verification of cas no

The CAS Registry Mumber 4519-90-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4519-90:
(6*4)+(5*5)+(4*1)+(3*9)+(2*9)+(1*0)=98
98 % 10 = 8
So 4519-90-8 is a valid CAS Registry Number.
