Check Digit Verification of cas no

The CAS Registry Mumber 1236252-99-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,2,5 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1236252-99:
(9*1)+(8*2)+(7*3)+(6*6)+(5*2)+(4*5)+(3*2)+(2*9)+(1*9)=145
145 % 10 = 5
So 1236252-99-5 is a valid CAS Registry Number.
