Check Digit Verification of cas no
The CAS Registry Mumber 1328-24-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1328-24:
(6*1)+(5*3)+(4*2)+(3*8)+(2*2)+(1*4)=61
61 % 10 = 1
So 1328-24-1 is a valid CAS Registry Number.
