Check Digit Verification of cas no

The CAS Registry Mumber 243124-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,1,2 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 243124-05:
(8*2)+(7*4)+(6*3)+(5*1)+(4*2)+(3*4)+(2*0)+(1*5)=92
92 % 10 = 2
So 243124-05-2 is a valid CAS Registry Number.
