Check Digit Verification of cas no

The CAS Registry Mumber 53019-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,0,1 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53019-97:
(7*5)+(6*3)+(5*0)+(4*1)+(3*9)+(2*9)+(1*7)=109
109 % 10 = 9
So 53019-97-9 is a valid CAS Registry Number.
