Check Digit Verification of cas no

The CAS Registry Mumber 1241820-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,8,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1241820-22:
(9*1)+(8*2)+(7*4)+(6*1)+(5*8)+(4*2)+(3*0)+(2*2)+(1*2)=113
113 % 10 = 3
So 1241820-22-3 is a valid CAS Registry Number.
