Check Digit Verification of cas no

The CAS Registry Mumber 256451-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,4,5 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 256451-17:
(8*2)+(7*5)+(6*6)+(5*4)+(4*5)+(3*1)+(2*1)+(1*7)=139
139 % 10 = 9
So 256451-17-9 is a valid CAS Registry Number.
