Check Digit Verification of cas no
The CAS Registry Mumber 4940-40-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4940-40:
(6*4)+(5*9)+(4*4)+(3*0)+(2*4)+(1*0)=93
93 % 10 = 3
So 4940-40-3 is a valid CAS Registry Number.
