Check Digit Verification of cas no
The CAS Registry Mumber 4813-02-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,1 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4813-02:
(6*4)+(5*8)+(4*1)+(3*3)+(2*0)+(1*2)=79
79 % 10 = 9
So 4813-02-9 is a valid CAS Registry Number.
