Check Digit Verification of cas no

The CAS Registry Mumber 145223-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,2 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 145223-72:
(8*1)+(7*4)+(6*5)+(5*2)+(4*2)+(3*3)+(2*7)+(1*2)=109
109 % 10 = 9
So 145223-72-9 is a valid CAS Registry Number.
