Check Digit Verification of cas no
The CAS Registry Mumber 4998-82-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4998-82:
(6*4)+(5*9)+(4*9)+(3*8)+(2*8)+(1*2)=147
147 % 10 = 7
So 4998-82-7 is a valid CAS Registry Number.
