Check Digit Verification of cas no

The CAS Registry Mumber 1245720-74-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,7,2 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1245720-74:
(9*1)+(8*2)+(7*4)+(6*5)+(5*7)+(4*2)+(3*0)+(2*7)+(1*4)=144
144 % 10 = 4
So 1245720-74-4 is a valid CAS Registry Number.
