Check Digit Verification of cas no

The CAS Registry Mumber 144730-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,3 and 0 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 144730-55:
(8*1)+(7*4)+(6*4)+(5*7)+(4*3)+(3*0)+(2*5)+(1*5)=122
122 % 10 = 2
So 144730-55-2 is a valid CAS Registry Number.
