Check Digit Verification of cas no
The CAS Registry Mumber 540493-06-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,4,9 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 540493-06:
(8*5)+(7*4)+(6*0)+(5*4)+(4*9)+(3*3)+(2*0)+(1*6)=139
139 % 10 = 9
So 540493-06-9 is a valid CAS Registry Number.
