Check Digit Verification of cas no

The CAS Registry Mumber 1431851-25-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,8,5 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1431851-25:
(9*1)+(8*4)+(7*3)+(6*1)+(5*8)+(4*5)+(3*1)+(2*2)+(1*5)=140
140 % 10 = 0
So 1431851-25-0 is a valid CAS Registry Number.
