Check Digit Verification of cas no

The CAS Registry Mumber 1240347-81-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,3,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1240347-81:
(9*1)+(8*2)+(7*4)+(6*0)+(5*3)+(4*4)+(3*7)+(2*8)+(1*1)=122
122 % 10 = 2
So 1240347-81-2 is a valid CAS Registry Number.
