Check Digit Verification of cas no
The CAS Registry Mumber 2481-94-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,8 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2481-94:
(6*2)+(5*4)+(4*8)+(3*1)+(2*9)+(1*4)=89
89 % 10 = 9
So 2481-94-9 is a valid CAS Registry Number.
