Check Digit Verification of cas no

The CAS Registry Mumber 21880-95-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,8 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21880-95:
(7*2)+(6*1)+(5*8)+(4*8)+(3*0)+(2*9)+(1*5)=115
115 % 10 = 5
So 21880-95-5 is a valid CAS Registry Number.
