Check Digit Verification of cas no

The CAS Registry Mumber 1256161-65-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,1,6 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1256161-65:
(9*1)+(8*2)+(7*5)+(6*6)+(5*1)+(4*6)+(3*1)+(2*6)+(1*5)=145
145 % 10 = 5
So 1256161-65-5 is a valid CAS Registry Number.
