Check Digit Verification of cas no

The CAS Registry Mumber 1263305-89-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,3,0 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1263305-89:
(9*1)+(8*2)+(7*6)+(6*3)+(5*3)+(4*0)+(3*5)+(2*8)+(1*9)=140
140 % 10 = 0
So 1263305-89-0 is a valid CAS Registry Number.
