Check Digit Verification of cas no
The CAS Registry Mumber 28320-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,2 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28320-33:
(7*2)+(6*8)+(5*3)+(4*2)+(3*0)+(2*3)+(1*3)=94
94 % 10 = 4
So 28320-33-4 is a valid CAS Registry Number.
