Check Digit Verification of cas no
The CAS Registry Mumber 25063-02-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,0,6 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 25063-02:
(7*2)+(6*5)+(5*0)+(4*6)+(3*3)+(2*0)+(1*2)=79
79 % 10 = 9
So 25063-02-9 is a valid CAS Registry Number.
