Check Digit Verification of cas no

The CAS Registry Mumber 71023-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,0,2 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71023-09:
(7*7)+(6*1)+(5*0)+(4*2)+(3*3)+(2*0)+(1*9)=81
81 % 10 = 1
So 71023-09-1 is a valid CAS Registry Number.
