Check Digit Verification of cas no

The CAS Registry Mumber 1219467-78-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,4,6 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1219467-78:
(9*1)+(8*2)+(7*1)+(6*9)+(5*4)+(4*6)+(3*7)+(2*7)+(1*8)=173
173 % 10 = 3
So 1219467-78-3 is a valid CAS Registry Number.
