Check Digit Verification of cas no

The CAS Registry Mumber 105143-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,1,4 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 105143-21:
(8*1)+(7*0)+(6*5)+(5*1)+(4*4)+(3*3)+(2*2)+(1*1)=73
73 % 10 = 3
So 105143-21-3 is a valid CAS Registry Number.
