Check Digit Verification of cas no
The CAS Registry Mumber 4984-82-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 4 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4984-82:
(6*4)+(5*9)+(4*8)+(3*4)+(2*8)+(1*2)=131
131 % 10 = 1
So 4984-82-1 is a valid CAS Registry Number.
