Check Digit Verification of cas no

The CAS Registry Mumber 17825-86-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,2 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17825-86:
(7*1)+(6*7)+(5*8)+(4*2)+(3*5)+(2*8)+(1*6)=134
134 % 10 = 4
So 17825-86-4 is a valid CAS Registry Number.
