Check Digit Verification of cas no
The CAS Registry Mumber 103026-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,0,2 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103026-09:
(8*1)+(7*0)+(6*3)+(5*0)+(4*2)+(3*6)+(2*0)+(1*9)=61
61 % 10 = 1
So 103026-09-1 is a valid CAS Registry Number.
