Check Digit Verification of cas no

The CAS Registry Mumber 519019-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,0,1 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 519019-35:
(8*5)+(7*1)+(6*9)+(5*0)+(4*1)+(3*9)+(2*3)+(1*5)=143
143 % 10 = 3
So 519019-35-3 is a valid CAS Registry Number.
