Check Digit Verification of cas no

The CAS Registry Mumber 1219685-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,6,8 and 5 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1219685-34:
(9*1)+(8*2)+(7*1)+(6*9)+(5*6)+(4*8)+(3*5)+(2*3)+(1*4)=173
173 % 10 = 3
So 1219685-34-3 is a valid CAS Registry Number.
