The CAS Registry Mumber 12225-91-1 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 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12225-91:
(7*1)+(6*2)+(5*2)+(4*2)+(3*5)+(2*9)+(1*1)=71
71 % 10 = 1
So 12225-91-1 is a valid CAS Registry Number.
