Check Digit Verification of cas no

The CAS Registry Mumber 27561-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,5,6 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 27561-18:
(7*2)+(6*7)+(5*5)+(4*6)+(3*1)+(2*1)+(1*8)=118
118 % 10 = 8
So 27561-18-8 is a valid CAS Registry Number.
