Check Digit Verification of cas no
The CAS Registry Mumber 28230-40-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,3 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28230-40:
(7*2)+(6*8)+(5*2)+(4*3)+(3*0)+(2*4)+(1*0)=92
92 % 10 = 2
So 28230-40-2 is a valid CAS Registry Number.
