Check Digit Verification of cas no

The CAS Registry Mumber 1425544-56-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,5,5,4 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1425544-56:
(9*1)+(8*4)+(7*2)+(6*5)+(5*5)+(4*4)+(3*4)+(2*5)+(1*6)=154
154 % 10 = 4
So 1425544-56-4 is a valid CAS Registry Number.
