Check Digit Verification of cas no

The CAS Registry Mumber 1253909-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,9,0 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1253909-20:
(9*1)+(8*2)+(7*5)+(6*3)+(5*9)+(4*0)+(3*9)+(2*2)+(1*0)=154
154 % 10 = 4
So 1253909-20-4 is a valid CAS Registry Number.
