Check Digit Verification of cas no
The CAS Registry Mumber 12227-62-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,2 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12227-62:
(7*1)+(6*2)+(5*2)+(4*2)+(3*7)+(2*6)+(1*2)=72
72 % 10 = 2
So 12227-62-2 is a valid CAS Registry Number.
