Check Digit Verification of cas no
The CAS Registry Mumber 12028-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,2 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12028-48:
(7*1)+(6*2)+(5*0)+(4*2)+(3*8)+(2*4)+(1*8)=67
67 % 10 = 7
So 12028-48-7 is a valid CAS Registry Number.
