5Check Digit Verification of cas no
The CAS Registry Mumber 8004-75-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.Calculate Digit Verification of CAS Registry Number 8004-75:
(6*8)+(5*0)+(4*0)+(3*4)+(2*7)+(1*5)=79
79 % 10 = 9
So 8004-75-9 is a valid CAS Registry Number.
