Check Digit Verification of cas no

The CAS Registry Mumber 1244030-70-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,4,0,3 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1244030-70:
(9*1)+(8*2)+(7*4)+(6*4)+(5*0)+(4*3)+(3*0)+(2*7)+(1*0)=103
103 % 10 = 3
So 1244030-70-3 is a valid CAS Registry Number.
