Check Digit Verification of cas no
The CAS Registry Mumber 545-91-5 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 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 545-91:
(5*5)+(4*4)+(3*5)+(2*9)+(1*1)=75
75 % 10 = 5
So 545-91-5 is a valid CAS Registry Number.
