Check Digit Verification of cas no

The CAS Registry Mumber 1210405-73-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,4,0 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1210405-73:
(9*1)+(8*2)+(7*1)+(6*0)+(5*4)+(4*0)+(3*5)+(2*7)+(1*3)=84
84 % 10 = 4
So 1210405-73-4 is a valid CAS Registry Number.
