Check Digit Verification of cas no

The CAS Registry Mumber 1147711-53-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,7,7,1 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1147711-53:
(9*1)+(8*1)+(7*4)+(6*7)+(5*7)+(4*1)+(3*1)+(2*5)+(1*3)=142
142 % 10 = 2
So 1147711-53-2 is a valid CAS Registry Number.
