Check Digit Verification of cas no
The CAS Registry Mumber 217459-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,4,5 and 9 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 217459-11:
(8*2)+(7*1)+(6*7)+(5*4)+(4*5)+(3*9)+(2*1)+(1*1)=135
135 % 10 = 5
So 217459-11-5 is a valid CAS Registry Number.
