Check Digit Verification of cas no

The CAS Registry Mumber 1191301-40-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,3,0 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1191301-40:
(9*1)+(8*1)+(7*9)+(6*1)+(5*3)+(4*0)+(3*1)+(2*4)+(1*0)=112
112 % 10 = 2
So 1191301-40-2 is a valid CAS Registry Number.
