Check Digit Verification of cas no

The CAS Registry Mumber 254453-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,4,4,5 and 3 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 254453-91:
(8*2)+(7*5)+(6*4)+(5*4)+(4*5)+(3*3)+(2*9)+(1*1)=143
143 % 10 = 3
So 254453-91-3 is a valid CAS Registry Number.
