Check Digit Verification of cas no
The CAS Registry Mumber 2998-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2998-99:
(6*2)+(5*9)+(4*9)+(3*8)+(2*9)+(1*9)=144
144 % 10 = 4
So 2998-99-4 is a valid CAS Registry Number.
