Check Digit Verification of cas no

The CAS Registry Mumber 1225072-50-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,5,0,7 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1225072-50:
(9*1)+(8*2)+(7*2)+(6*5)+(5*0)+(4*7)+(3*2)+(2*5)+(1*0)=113
113 % 10 = 3
So 1225072-50-3 is a valid CAS Registry Number.
