Check Digit Verification of cas no
The CAS Registry Mumber 939-09-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 939-09:
(5*9)+(4*3)+(3*9)+(2*0)+(1*9)=93
93 % 10 = 3
So 939-09-3 is a valid CAS Registry Number.
