Check Digit Verification of cas no

The CAS Registry Mumber 139219-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,1 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139219-91:
(8*1)+(7*3)+(6*9)+(5*2)+(4*1)+(3*9)+(2*9)+(1*1)=143
143 % 10 = 3
So 139219-91-3 is a valid CAS Registry Number.
