The CAS Registry Mumber 254-05-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,5 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 254-05:
(5*2)+(4*5)+(3*4)+(2*0)+(1*5)=47
47 % 10 = 7
