Check Digit Verification of cas no

The CAS Registry Mumber 1142349-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,2,3,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1142349-99:
(9*1)+(8*1)+(7*4)+(6*2)+(5*3)+(4*4)+(3*9)+(2*9)+(1*9)=142
142 % 10 = 2
So 1142349-99-2 is a valid CAS Registry Number.
