Check Digit Verification of cas no

The CAS Registry Mumber 161-25-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,6 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 161-25:
(5*1)+(4*6)+(3*1)+(2*2)+(1*5)=41
41 % 10 = 1
So 161-25-1 is a valid CAS Registry Number.
