Check Digit Verification of cas no
The CAS Registry Mumber 5425-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5425-83:
(6*5)+(5*4)+(4*2)+(3*5)+(2*8)+(1*3)=92
92 % 10 = 2
So 5425-83-2 is a valid CAS Registry Number.
