Check Digit Verification of cas no

The CAS Registry Mumber 119-70-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 119-70:
(5*1)+(4*1)+(3*9)+(2*7)+(1*0)=50
50 % 10 = 0
So 119-70-0 is a valid CAS Registry Number.
