Check Digit Verification of cas no

The CAS Registry Mumber 120422-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,2 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120422-49:
(8*1)+(7*2)+(6*0)+(5*4)+(4*2)+(3*2)+(2*4)+(1*9)=73
73 % 10 = 3
So 120422-49-3 is a valid CAS Registry Number.
