Check Digit Verification of cas no

The CAS Registry Mumber 1144031-16-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,4,0,3 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1144031-16:
(9*1)+(8*1)+(7*4)+(6*4)+(5*0)+(4*3)+(3*1)+(2*1)+(1*6)=92
92 % 10 = 2
So 1144031-16-2 is a valid CAS Registry Number.
