Check Digit Verification of cas no

The CAS Registry Mumber 1140912-46-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,0,9,1 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1140912-46:
(9*1)+(8*1)+(7*4)+(6*0)+(5*9)+(4*1)+(3*2)+(2*4)+(1*6)=114
114 % 10 = 4
So 1140912-46-4 is a valid CAS Registry Number.
