Check Digit Verification of cas no

The CAS Registry Mumber 942229-73-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,2,2 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 942229-73:
(8*9)+(7*4)+(6*2)+(5*2)+(4*2)+(3*9)+(2*7)+(1*3)=174
174 % 10 = 4
So 942229-73-4 is a valid CAS Registry Number.
