Check Digit Verification of cas no

The CAS Registry Mumber 1403990-53-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,9,9 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1403990-53:
(9*1)+(8*4)+(7*0)+(6*3)+(5*9)+(4*9)+(3*0)+(2*5)+(1*3)=153
153 % 10 = 3
So 1403990-53-3 is a valid CAS Registry Number.
