Check Digit Verification of cas no

The CAS Registry Mumber 425669-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,5,6,6 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 425669-40:
(8*4)+(7*2)+(6*5)+(5*6)+(4*6)+(3*9)+(2*4)+(1*0)=165
165 % 10 = 5
So 425669-40-5 is a valid CAS Registry Number.
