Check Digit Verification of cas no

The CAS Registry Mumber 22933-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,3 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22933-71:
(7*2)+(6*2)+(5*9)+(4*3)+(3*3)+(2*7)+(1*1)=107
107 % 10 = 7
So 22933-71-7 is a valid CAS Registry Number.
