Check Digit Verification of cas no

The CAS Registry Mumber 1262889-69-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,8,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1262889-69:
(9*1)+(8*2)+(7*6)+(6*2)+(5*8)+(4*8)+(3*9)+(2*6)+(1*9)=199
199 % 10 = 9
So 1262889-69-9 is a valid CAS Registry Number.
