Check Digit Verification of cas no
The CAS Registry Mumber 12224-98-5 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 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12224-98:
(7*1)+(6*2)+(5*2)+(4*2)+(3*4)+(2*9)+(1*8)=75
75 % 10 = 5
So 12224-98-5 is a valid CAS Registry Number.
