Check Digit Verification of cas no
The CAS Registry Mumber 549-56-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,4 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 549-56:
(5*5)+(4*4)+(3*9)+(2*5)+(1*6)=84
84 % 10 = 4
So 549-56-4 is a valid CAS Registry Number.
