Check Digit Verification of cas no

The CAS Registry Mumber 2027-81-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,2 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2027-81:
(6*2)+(5*0)+(4*2)+(3*7)+(2*8)+(1*1)=58
58 % 10 = 8
So 2027-81-8 is a valid CAS Registry Number.
