Check Digit Verification of cas no

The CAS Registry Mumber 256223-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,6,2,2 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 256223-25:
(8*2)+(7*5)+(6*6)+(5*2)+(4*2)+(3*3)+(2*2)+(1*5)=123
123 % 10 = 3
So 256223-25-3 is a valid CAS Registry Number.
