Check Digit Verification of cas no
The CAS Registry Mumber 643-84-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 643-84:
(5*6)+(4*4)+(3*3)+(2*8)+(1*4)=75
75 % 10 = 5
So 643-84-5 is a valid CAS Registry Number.
