Check Digit Verification of cas no

The CAS Registry Mumber 1281962-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,9,6 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1281962-19:
(9*1)+(8*2)+(7*8)+(6*1)+(5*9)+(4*6)+(3*2)+(2*1)+(1*9)=173
173 % 10 = 3
So 1281962-19-3 is a valid CAS Registry Number.
