Check Digit Verification of cas no

The CAS Registry Mumber 25200-15-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,0 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 25200-15:
(7*2)+(6*5)+(5*2)+(4*0)+(3*0)+(2*1)+(1*5)=61
61 % 10 = 1
So 25200-15-1 is a valid CAS Registry Number.
