Check Digit Verification of cas no

The CAS Registry Mumber 1263273-29-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,2,7 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1263273-29:
(9*1)+(8*2)+(7*6)+(6*3)+(5*2)+(4*7)+(3*3)+(2*2)+(1*9)=145
145 % 10 = 5
So 1263273-29-5 is a valid CAS Registry Number.
