Check Digit Verification of cas no
The CAS Registry Mumber 546-97-4 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 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 546-97:
(5*5)+(4*4)+(3*6)+(2*9)+(1*7)=84
84 % 10 = 4
So 546-97-4 is a valid CAS Registry Number.
