Check Digit Verification of cas no

The CAS Registry Mumber 140146-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,1,4 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 140146-90:
(8*1)+(7*4)+(6*0)+(5*1)+(4*4)+(3*6)+(2*9)+(1*0)=93
93 % 10 = 3
So 140146-90-3 is a valid CAS Registry Number.
