Check Digit Verification of cas no

The CAS Registry Mumber 1349903-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,9,9,0 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1349903-34:
(9*1)+(8*3)+(7*4)+(6*9)+(5*9)+(4*0)+(3*3)+(2*3)+(1*4)=179
179 % 10 = 9
So 1349903-34-9 is a valid CAS Registry Number.
