Check Digit Verification of cas no
The CAS Registry Mumber 516493-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,6,4,9 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 516493-93:
(8*5)+(7*1)+(6*6)+(5*4)+(4*9)+(3*3)+(2*9)+(1*3)=169
169 % 10 = 9
So 516493-93-9 is a valid CAS Registry Number.
