Check Digit Verification of cas no
The CAS Registry Mumber 1100905-45-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,0,9,0 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1100905-45:
(9*1)+(8*1)+(7*0)+(6*0)+(5*9)+(4*0)+(3*5)+(2*4)+(1*5)=90
90 % 10 = 0
So 1100905-45-0 is a valid CAS Registry Number.
