Check Digit Verification of cas no

The CAS Registry Mumber 220174-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,7 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 220174-30:
(8*2)+(7*2)+(6*0)+(5*1)+(4*7)+(3*4)+(2*3)+(1*0)=81
81 % 10 = 1
So 220174-30-1 is a valid CAS Registry Number.
