Check Digit Verification of cas no

The CAS Registry Mumber 1340548-72-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,5,4 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1340548-72:
(9*1)+(8*3)+(7*4)+(6*0)+(5*5)+(4*4)+(3*8)+(2*7)+(1*2)=142
142 % 10 = 2
So 1340548-72-2 is a valid CAS Registry Number.
