Check Digit Verification of cas no

The CAS Registry Mumber 1253840-59-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,8,4 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1253840-59:
(9*1)+(8*2)+(7*5)+(6*3)+(5*8)+(4*4)+(3*0)+(2*5)+(1*9)=153
153 % 10 = 3
So 1253840-59-3 is a valid CAS Registry Number.
