Check Digit Verification of cas no

The CAS Registry Mumber 918943-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,9,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 918943-73:
(8*9)+(7*1)+(6*8)+(5*9)+(4*4)+(3*3)+(2*7)+(1*3)=214
214 % 10 = 4
So 918943-73-4 is a valid CAS Registry Number.
