3-4Check Digit Verification of cas no
The CAS Registry Mumber 1328-19-4 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, 1 and 9 respectively.Calculate Digit Verification of CAS Registry Number 1328-19:
(6*1)+(5*3)+(4*2)+(3*8)+(2*1)+(1*9)=64
64 % 10 = 4
So 1328-19-4 is a valid CAS Registry Number.
