Check Digit Verification of cas no
The CAS Registry Mumber 111923-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,9,2 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 111923-06:
(8*1)+(7*1)+(6*1)+(5*9)+(4*2)+(3*3)+(2*0)+(1*6)=89
89 % 10 = 9
So 111923-06-9 is a valid CAS Registry Number.
