Check Digit Verification of cas no

The CAS Registry Mumber 20476-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,7 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20476-40:
(7*2)+(6*0)+(5*4)+(4*7)+(3*6)+(2*4)+(1*0)=88
88 % 10 = 8
So 20476-40-8 is a valid CAS Registry Number.
