5Check Digit Verification of cas no
The CAS Registry Mumber 12167-45-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,6 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 12167-45:
(7*1)+(6*2)+(5*1)+(4*6)+(3*7)+(2*4)+(1*5)=82
82 % 10 = 2
So 12167-45-2 is a valid CAS Registry Number.
