Check Digit Verification of cas no
The CAS Registry Mumber 12223-42-6 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 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 12223-42:
(7*1)+(6*2)+(5*2)+(4*2)+(3*3)+(2*4)+(1*2)=56
56 % 10 = 6
So 12223-42-6 is a valid CAS Registry Number.
